Does this boy like me?

ok well, theres this boy. and yes that's another one of those type of questions. well, theres this boy in my homeroom, band cl, and 2 lockers away from me. i want to know if he likes me back because well, here's some things he does. He always talks to me, when we are looking each other in the eyes he looks away quickly, he looks at me in cl, and he always tells me jokes. I don't know if they are saying he likes me or not. so can someone tell me how boys wil act if they like you or if he likes me. thanks :D
