You are not a douche.. . You don't like fat girls and you have every right. I'd tell her like this.. "look fatty.. I complemented your hair that doesn't mean I like you, so leave me the hell alone" ok maybe not as harsh but make sure she gets the message.
Because overweight girls are very insecure & they'll get attached to anyone thats nice to them. Good luck getting her off you. LOL!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
