Being a girl, I know plenty about things like this: 1.) smile. Girls love it when they catch you looking, and instead of looking away, you smile right at them. 2.)Text her. If you do have a phone, text her, dont wait, she might be waiting on the other end for a text that wont come 3.)Talk and hang out with her. Yeah you have your own friends and thats cool but if you hang out with her as well, she will start to understand (guys are really fun to hang out with) Good Luck!
