Like this guy.. need help a bit? Please : ]?

Hi, I like this guy at my school, ... He's a Juniour, and I'm a freshman. I see him every morning sometimes, when I'm alone, and he's alone also. He seems like the shy type you know.. cos' I rarely see him as outgoing or with much friends, I'm same way.. anyways. I Think he does notice me, and I DO wanna get to know him, he seems sweet and all and not the meanie type so yeah, but I'm way too shy. So I have P.E with him, but he's in a different cl, but same period. He was running track while we had our hurrdle thing going on, and I think he knows he sees me there before, but while hes running he sped up like SPRINTINGGGGGGGGGGG FASTT I was like O_______O... ok. He Always, seems like to walk like, robot like its WEIRD! He dosn't look my way when hes walking, even when he knows I hang by the same spot everyday at lunch, I can't just. Smile O_o. One time he was behind this trr and I happend to hear his friend before the bell rang, "She's a freshman." O___o I DON'T KNOW WHAT TO DO! D: Plus I've never had a bf anyways I would'nt know how to react, or hint that I like him a bit.. or a lot : [
