pubs and clubs and acting my age...

I feel old. I shouldn't feel old. I am only 22 and on top of that my whole life I have always been the youngest person in my class. But I don't want to do things that 22 year olds want to do anymore, or, so it seems. Since coming to London there have been a multitude of "welcome events" most of which involve drinking obscene amounts of expensive alcohol and then going to clubs only to drink more obscene amounts of alcohol.

Now, I am always one up for clubbing, I love to dance. But for some reason I feel different about it here. The music is for the most part the same, very danceable, but I have no desire to 'party hard' on a Saturday night, or weekday night. Maybe I remember too well the mornings that follow such evenings or maybe my ideas of a good time have changed - who knows? All I know at the moment is that I would much rather go to a pub and chat, and drink maybe a beer, or two, instead. I would like to go to a place that is more relaxing, where I can hear what the other person is saying without having to go through a screaming match.

Am I prematurely aging? Currently I am a bit torn between enjoying a city renowned for its (although touristy) clubs and simply enjoying a much quieter night with the scenery of London or relaxing at a pub.
