have you seen this documentary? if you haven't, i recommend it. basically its a documentary that humanizes the different high school stereotypes... and it was good. i found all the characters to be highly likeable and i understood their reasons for doing the shit they did... except for one. the popular girl.
not to be cold or unforgiving; but the fact that your retarded sister killed herself in the basement two years ago isn't a valid reason for being a nasty bitch.
... see the movie.
