The fact that you don't give this stuff to girls is quite sad. WTF mate.
If I was you'd I'd come to class real early, and sit in seats right across from the hottest jailbait so they'd have to pass my desk to sit down. This way they would see me drawing beautiful art and be like "omg you're so talented. Can you draw me?" Pretty soon I'd have the whole class at my mercy. All the girls would want me to draw their picture, but I'd be sly and only draw pictures of a few THUS creating the jealousy factor. Girls would start fighting for my attention and then I'd start dropping bombs
Chick: Hey Phoenix *flirts* how come you don't draw anything for me *pouts*
Me: I wanted to...but she told me not to...
Chick: Who?
Me: I can't tell...she told me -
Chick: You can tell me anything. Want me to suck your dick?
