So, there's this guy, are you surprised, anyway he keeps messing with me during 7th period science. He must really enjoy playing with my feet or something because he won't quit. I mean what's the deal. Also, I wonder what he's thinking about continually. Especcially when he randomly smiles or looks likes he was just kicked or his dog died. I guess it wouldn't be such a big deal except the fact that he did reject me a week or two ago. I mean he says random things like "You're like a drug, Your soo addicting." I was just wondering what goes on in his head and why?

The boy is in love.

He is flirting with you, but seeing as he rejected you it might not be anything more than that.

He's probably a mess of thoughts. I love her - no I don't! She's so pretty, girls eww! Personally I'd stay away until he grew up a bit. Although sometimes you have to wait a while. I know guys in their twenties that still pull girl's hair. Oh dear...

Wow! So amazing. I hope he doesn't love me because I can't return the favor I'm afraid. Although he does make a startlingly convincing argument and I may fall for him if he doesn't stop. Lol. Well thanks for the help.

If you made it a point that you were interested in him, and was rejected, then I have a slightly different scenario to throw out here.
He may not be interested, but he knows you like him - which makes the flirting easier for him because he knows he won't be rejected.

He might be flirting around with you to keep you interested in him because it feels good to be liked by someone...
Even if you don't share the same feelings for that person... Thats just a thought though...

He could have had a chance to think about
You liking him and has decided that he likes you too.

Either way, good luck.
