Coming of age...
I will soon(ish) be 25. Now, I know that a fair bit of this number's coolness is based on the scarilly few number of times it divides 100 and 50, and that is just down to natures little foibles of giving us 10 fingers* but still, it is the first time I'll have been a square for a while**, and any excuse for a party, right?

What I actually want for my birthday is a ceilidh. Fiddling Around are playing in Cambridge on the 3rd of November, so I think I'm going to go to that. This post is a heads-up, a) so all you lovely people can decide that you want to come to a ceilidh with me and put the date in your diary, and b) so anyone who'd like to see me Saturday afternoon or for pre-ceilidh dinner when I'm back in Cambridge can shout now.

But that still leaves me with the weekend of my birthday. Any ideas? I have quite a good idea of what I don't want. I don't just want a random sit around and drink with people, because M is probably having one of those for his birthday, and people won't really come all the way to Coventry for two within a month. I don't want a big thing, or a readthrough, because it's one of the weekends straight after Middlemarch. I don't want a Long Journey, because it's just before I go to Alness***. I'd like something fun outdoors with a smallish group of friends (long walk, go ape, messing around in boats etc) but it's the Middle of October, so I'm not sure this is a good thing to plan. And I'm not sure any of these things are near Coventry. I've wondered about running a murder mystery party type thing, but I'm not quite convinced... All help greatfully recieved!

(As an aside, M and I were discussing parties in general, and seem to be oddly different. He said he wanted something low stress, so just some people sitting around drinking and talking. I said I found just people relaxing far more stressful than more timetabled / structured fun, like an afternoon of boardgames or a readthrough etc. He thinks I'm a mathmo freak now. I know I'm a mathmo freak ;-) but I didn't think I was alone in this - is it just me?)

Oh, and yes, I've just had a wonderful holiday and seen lots of lovely people, and may blog about it later.

*Yes, pedants, I know two of them are thumbs. What should I say? I was scared if I said digits that might include toes.

** Wouldn't it be cool if instead of having the milestone birthdays as multiples of 10 with a few extras like 21 and 18 we had the squares (1,4,9,16,25,36,49,64,81)?

*** My parents are moving to Alness. I can't remember if I told LJ this.

While I think you are a mathmo freak, I completely see where you're coming from. People sitting around and relaxing are worrying because you have to make sure they're OK and entertain them and Be A Good Host- whereas structured entertainment means there are Things for them to Do and they know what they're meant to be doing.

On the other hand, it's harder to go and hide for a few minutes.

It's an exciting time for ages. You're square this year. Next year, you'll be sandwiched between a square and a cube - that won't happen again in a hurry. Then you'll be a cube. Then you'll be perfect, like wot I am at the moment.

It gets boring after that. (Of course there's no such thing as a boring number... proof available upon request.)

That means I'm perfect too. Not that I can remember what a perfect number is! Aah, it's the one where factors sum to the number (says she after a bit vaguely remembering and checking). We're also triangular. (Is there a correlation between perfect and triangular or is this a rare occurrence?)

My dad has been known to declare that he is in his prime which we can use next year I think.

On Sally's birthday, I don't know. Being not in Cambridge or Coventry I'm probably unlikely to be available unfortunately.

Nice spot. I didn't realise this until checking just now (see the Wikipedia article on perfect numbers), but all perfect numbers are triangular. So we're perfect triangles.

Mathmo : all *even* perfect numbers are triangular. It is not known whether there exist any odd perfect numbers, although so far, no-one's found any.

Are all even triangular numbers perfect? No because 10 isn't.

I wondered because I noticed that 6 and 28 were both perfect.

The even perfect numbers have a one-to-one correspondance with the Mersenne primes. For each Mersenne prime 2^p - 1, where p itself is prime, then 2^p - 2 is a perfect number.

There are about 44 known Mersenne primes, and hence there are 44 known perfect numbers. Whereas triangular numbers are much more common.

29=prime. 30=product of first three primes. 31=prime. 32=25. I think 33 is the next candidate boring number l-)

So suppose we've found something interesting about all the numbers up to including 32, and we declare 33 to be 'boring'. But then it's the first 'boring' number. That in itself is quite interesting... :-)

I find it a bit strange when structured fun is all or almost all that there is. I.e. when people organise things that are 95% readthrough and 5% general chat. I don't really understand why one would want to gather lots of friends around and not spend a significant portion of time chatting to them. But I do understand why one might want some structure - particularly if there are people present who don't know many people.

Indeed. Especially if (as some people did) they get Dreadfully Hurt if you don't find the Great Activity that Everyone WILL Enjoy particularly enjoyable.

I think if you're told "this is a foo party" (where foo is dancing, or singing, or a particular readthrough, or dressing up, or playing guitar hero or whatever) and you turn up and whinge that you don't like foo, then it is a bit upsetting to the host. Or at least, if not upsetting, then inclined to leave one puzzling over why the unhappy person bothered to come.

You can get into interesting situations where you would really like to see the host, but the host proposes an activity you hate. In those circumstances, I think most people would feel the polite thing to do would be to go to the party. In which case, whingeing about the foo would be impolite, but at the same time, the host should be OK if not everyone joins in with the foo.

I think we just disagree. If you're having a foo party, where the majority of the day is the foo, it can be really annoying and upsetting to have someone turn up who is not joining in with the foo. It's one thing if you say "I'm having a party" and then once you have some willing victims tell them they are going to foo, in which case the host should be OK if not everyone joins in. But if you say "I am going to foo" and a friend turns up who does not foo, then I spend a lot of time worrying about them, about whether they're happy (I mean, they're probably not happy if everyone else is fooing and ignoring them because they are not) and I have to stop fooing to go and check on the non-fooing guest, which is a pain because (one assumes) I quite like fooing if I organised a foo party in the first place.

I don't think that if people want to see me their only option is to go to my foo-party!

(Yes, this does depend on what foo is. Obviously if foo is a karioke party, then there is usually only one person singing while a lot of people sit around and chat, so it's probably OK to go to a karioke party and not sing, because you can just sit around and chat with the other people who are not singing. And it does depend on what % of the time the foo takes up.)

What you've said is fine, but then must promise not to be offended or upset when you get a reply saying, "thank you for the invite to foo with you, but I won't be coming as I don't like fooing". Otherwise the non-fooer can't win.

(I am enjoying having a non-compsci conversation with foo as the primary verb.) :-)

I agree with you, for what it's worth. And, if I want to go to parties that have more of a foo/non-foo balance, it's up to me to organise them.

But, I also think that, it is perhaps to be avoided to have a 90% + foo party for something like a birthday because it excludes non-foo loving friends.

If the foo-party was the only way to spend time with someone, I would probably be quite happy turning up, not-fooing and getting the time I could with the person I was there to see. Reading (or these days baby-wrangling) would be my favourite nonfoo way of passing the time, and if someone who was SUPPOSED to be enjoying themselves kept interrupting to see if I was ok, I might start getting sarcastic after a bit.

Mind you, I once got grumped at for daring to state a) I didn't like what a large group of people were watching and b) opting to sit and read somewhere else rather than sit through it. This was apparently "unsociable" of me.

I expect you to have the world's biggest party on your 36th and 48th birthdays, and possibly 30 and 42 as well. In fact 30 should be biggest because it's important for you and the five-fingered people.

Ah, you baby... I am so much older then you have ever yet been :-)

Whatever you do for the weekend of your birthday, please count me (and possibly boy?) in, as won't make dancing fun. 3rd Nov is two friends' wedding and I will be in Stratford. But want to help celebrate your squaring!

On the weekend of 3rd November, I will be celebrating my mum's 50th Birthday by spending a weekend with her and her 4 sisters (who I have nothing in common with) at a (very overpriced) spa hotel in Staffordshire. How I wish I could decline and come to your ceilidh instead. Birthday weekend good for activities though (you said it wouldn't be the weekend of 20th October, didn't you).

Your birthday is on Tuuesday the 16th of October, right? (Or your profile lies.) By "The weekend of your birthday" do you mean the 13th-14th or the 20th-21st? If the former, I am actually in the country for a CAAT meeting on the Saturday. I will be busy during the day, but free the evening and the Sunday, and could conceivably come up to Cov.

I like the idea of a murder mystery.

"He thinks I'm a mathmo freak now."
Kind of off topic from the rest of your post, but Adrian said something similar to this to me the other day. "You really are a geek, aren't you" he said, clearly amused. I don't even remember what we were talking about - possibly me waxing lyrical about walking around the particle accelerator in CERN (which was super cool and by far the best school trip I've ever been on).

You should have included the dictionary definition of "finger" in your footnote which admits that it may include thumbs. I find that knee-jerk pedantry ("ten items or less" and the like) is one of the more irritating geek traits!

Nah. I'm not a mathmo freak and I have a similar reaction. I like just hanging around talking but I get edgy if 1) there isn't a known general time limit, and 2) I don't have something to do with my hands if the conversation turns to something that bores me. *shrug*

And BAH for not being able to come to the ceilidh because it's so close to Buffycamp! BAH say I!

And to answer the actual question: all social interaction is energy-sapping and stressful, and it makes no odds whether it's structured or not, but I wouldn't stop doing structured or non-structured interaction just because of that. Actually structured ones are sometimes ones I've organised, so I prefer the other kind in that case, because I don't have to be keeping an eye on things, but if somebody else is watching the time, either is good.

I get called a Mathmo despite not being one! Obviously I exhibit enough of the characteristics of a Mathmo freak to confuse people.

Although I did manage to confuse a friend of a friend into thinking I did English recently.
