Really weird / scary / sad.
First observation: most chavs don't 'do' facebook really. They all have about 4 tagged photographs and only ever use it to 'like' things like "if id av known u were gna waste my tym i wudnt av shagd u".
Moreover, it's so weird to see people who are your age with actual careers. Most of them are in trades, some soldiers etc.
My all-time enemy from Primary School right through to leaving high school is now an Actual Cage Fighter. I'm definitely glad we never had the fight that almost happened every Thursday after PSHE!
