People often become less shy around the one they love though. I know because I'm that sort of person myself.

That being said, someone definitely has to start the ball rolling, so you have to get over your fear and find a way to approach these kinds of girl. Actually, one of these kinds of girl had a thing for me once. Her method was to have her friend ask me... the main thing I remember here is that it wasn't a good way to go about it. At the time I would have preferred the old fashioned note in the locker.
