Does this mean that this guy likes me?

Theres this guy and i like him but i dont know if he likes me or not.We sit together in some subjects and we talk the whole time even if the teacher tells us to SHUT UP! we laugh about random stuff and i tease him about looking like a vampire and we have a laugh.but when we go to our lockers we dont talk that much just get our stuff and go and we dont sit together all the time just in some cles.and we dont see each other at lunch or recess. So is it possible that he likes me?
