Hey, girls need your help?

There's this girl named Martha in my cl who always stares at me, and when i turn to see what she wants shell just turn away. and another thing is when she sees me in the hall shell just giggle. but she really doesn't take the time to talk to me on her free time. this is what happens with a lot of the girls . ive recently took up modeling and of course im could all kinds of names be the guys but the girls seem to like it.... please tell me what you think girls.
