OMG!!!!IM SOO INLUV WITH THIS GUY! WHAT SHOULD I DO? HE DIDN'T EVEN NOTICE ME! AND HE MAY THOUGHT IM A FREAK!?

ok, so i really like this nine grader and with just my luck ,he set at my about back in culture and developments cl. He barely noticed me, or he either thought Im a freak. He's not really cute but I think he's really great! He knows a lot of things and his voice is fab. So.....what should I do to grab his attention? Like in a good way? without seeming like I'm trying? What should I do with this kinda guy?
