What does the guy's pat on the head mean?

Anonymous
So there's this guy in school who is a grade higher than me. I knew from my friends and his too and from the signs he is giving me that he likes me. I know for a fact that he rarely pats a girls head when he meets her. But I noticed that he pats mine more often and he even ruffles my hair. The weird thing is, I'm beginning to like him too and whenever we meet each other he pats and ruffles my head. We meet each other everyday in school, and whenever we do, we're always surrounded by people who wants to tease us just for being together.
