I don't think I've really had a lot of expectations about life so far... I remember at primary school thinking that GCSE's seemed an impossibly long time away, and I thought the same thing about A levels and leaving school when I got to GCSE's...
Stuff like marriage, kids, my own house etc has never really seemed like a real possibility until I thought about it recently, when I realised how fast life is going. I'm still not really sure what I expect though. I think I had some vague notions of being an architect and designing really awesome buildings when I was younger, but that hasn't worked out either - I'm coming to the end of my first year in a (hopefully) 4 year Engineering degree, although my sister is looking to do architecture at university.
I expected I'd get a girlfriend at some point ("Oh, everyone has girlfriends now, I'm sure to have got the balls to go and ask someone out by the end of next year"), which never happened, and I expected that I'd morph into a 'lad' when I got to uni, which also hasn't happened. I expected that the second term of uni would be just like the fist one, and it wasn't, probably mainly because someone in my social group dropped out. I liked it better when he was here. I didn't expect to get along with any English students, which again, went against expectations... I'm not sure there are many things that turned out as I expected! I've met lots of interesting people who are very different to anyone I ever knew at school - I didn't realise how limited my sample of humans was until I came to uni!
I suppose if I try and delve deep enough there are bound to be thousands of little things that aren't as I expected, but in broad terms, I suppose I had some vague notion of doing well at school, and going to uni, which I have done, and I had vague notions of getting a girlfriend, which I haven't done.
I don't really have many expectations for the future either to be honest - I imagine just sort of coasting through the rest of uni, graduating, going into some kind of average engineering job, getting old, paying taxes, and dying.
