all i have to say is that girls are evil
I have had this happen to me and yes im ashamed to say i've done it to others
Teachers don't know how to deal with it or stop it, the only way to really win over is to be the b*t*h*e*t and well i learnt to be pretty good at that
the way i delt with it was to find a true group of friends, and yes it may still go on at small levels, but it an easily be dealt with and things are mostly teacakes and flowers ;)
