does he like me?

ok. So this boy my bff and I think likes me. Here are some things he has done. He begged the PE teacher for me to be on his team, he put his hand on my shoulder for like 20 seconds while talking to me, I caught him staring at me so he smiled and waved. He goes to the back of the line to talk to me. I know you guys are probably gonna say yes but he might not because he also one time teased me about my hair.
