I dont think girls like me?

let me see. I'm not a full super intelligent nerd and im into star wars. alot. it's my personal influence like an artists thoughts to a painting. some girls have even asked me out. no lie. 2 on the same occasion. they were okay but i said no. why. because back then i was a royal subject of fun for people. now however im just a comedian. and a biotechnologist in training. But thats another part of this story. I asked out 2 girls at school once. the 1st said yes but said no she couldn't go out 22hours later because the school wouldn't allow her to (she was an exchange student from denmark). more to the point others probably said i was stupid.the second declined. i wrote both of them notes with calligraphy and went to the trouble of delivering to them shaking furiously. i was scare. but i fought. i don't know what girls like. i am compionate, respectful, and lack any dignity due to my love for making those around me laugh. i don't swear or act inappropriately.what can i do.
