Just ask her if she would like to hang out sometime. This puts her at ease, and lowers her defensiveness at her young age. Most young girls are afraid of committment, so don't seem so serious. Also make her laugh. If she likes to talk on the computer use that to your advantage. That's called putting someone together,and it works. If you aren't sure what she thinks of you give it a shot. Observe her body language towards you at school. If she doesn't make eye contact with you at school and she isn't a shy person that chances are she is not interested or is scared of boys. If she is scared of boys you need that kinda drama in your life anyways. If she goes out her way to talk to you, and says hi to you, then chances are she likes you. Remember the first one to speak loses. Just shut up listen and learn. Observe her, and then make your move. Good luck and let me know how it works.
