Just act confident...... And feel confident, and then you won't look like a fool. But don't be TOO confident, or the girl will think you're a douche. And just be yourself, I guess. I know everyone says that, but everyone says it 'cause it's true. Good luck! :)
Ask her out for a drink or to a nightclub or maybe to see a film at the cinema. You could say you like hanging out with her and enjoy being in her company.
Haha there is no how you wouldnt look werid... Or act shy.. Becus of fear of rejectionn... But still act brave or ask quickly ecttt..
"hey , you alright"? (say tht to her first!) and when she replies "yeh" just say "okay , I was jus wondering , that , ...I think you're really nice and I like you"..8)
