Our school didn't seem to divide like that, there were people who were pretty brainy, who fitted in because they wouldn't be walked over, whereas there were others who didn't fit in because they couldn't relate to the lower set kids. It never really seemed to me to be a question of the 'type' of person as such, just how much they isolated themselves from everyone else.
There was one kid who was huge on James Bond, even had a James Bond Bag, talked about Bond all the time, and got tortured mercilessly over it. He was quite a clever kid, and no-one minds if he likes James Bond, but like all things in life there's a limit. It's like the difference between someone who likes, for example, Call of Duty, and someone who won't shut up about it.
