Also, don't worry about what other people think about the person -guys have a tendency to not ask a girl out if they think others will disapprove. If you like someone, ask them out -if your friends give you a hard time, ask that they respect you and the other -if they don't, drop them -not the girl. Check your own mind, too -many have ideas about beauty and attractiveness in their heads that aren't their own due to advertising/TV/movies, peer pressure, etc.
