Going off Doffcockers point about school, i was the captain of the Basketball team in my year and the year above (mainly because i was very tall for my age) and the team spirit shown to me by older lads was fantastic.
they didn't ostracise me because i was younger than them and was taking one of their mates places in the team, they rallyed round.
Now football on the other hand was a whole different kettle of fish, i was, admittedly crap at football, it's not my sport, i use my hands not my feet, but during any P.E lessons where i was in a team with any players from the school football team i was routinely abused and bullied.
l won't tar everyone because thats unfair but using my school purely on it's own, football was the sport that attracted the lowlife chavs, bullies and abusers. 2 People on the football team beat my mate up because he died his hair black one year, i mean how low do you really have to be to do that.
