I went to the local comp and had very few friends there - am only in touch with one school friend. I had some v good friends at the boys' grammar school in town, and used to spend Friday/Saturday/Sunday socialising with them. When this got out at school, I had a meteoric rise in the popularity stakes with all of the girls in the "in crowd" desperate to come to cool bars and parties in town. I didn't invite them.
Still in touch with a couple of the boys, and going out for dinner with them next month.
I was very swotty at school till the age of 13, when I was given a maths O level mock exam, with a view to taking it 2 years early. I got 9% and gave up after that. I was bored with it all and just wanted to leave. Stayed for A levels, cocked them up, got a job "to pay back some of the money spent on me over the years"
and promptly moved out to share a house in London.
My school was quite, quite bonkers, in that no-one could be seen to fail at anything, so we did no competitive sport, no house points etc etc. If you wanted to come to lessons, that was fine, if you didn't, well that was fine too.
