When a person is unpopular, and is given a hard time, the majority of people change their outlook and try to fit in.
Some people however are so self centred, that when someone has a go at them for being a twit they think. 'I'm perfect I am, I know everything I do, my taste is impeccable, there can't be anything wrong with me.
I know, it must be the people I like they're attacking, not me, what a load of plebs, they've got no taste. I mean it couldn't be me could it, I'm perfect aren't I ?'
