Search Results: how to tell he his hiding something

There's this boy I sit next to in History and Science and all my friends keep winding me up, telling me he likes me. Basically they keep telling me this because of a few events that have occurred.

In science and history, he's always talking to me, trying to make me laugh. He also pointed out something I did that I didn't even notice I did which was kind of strange. He never used to wear anything but recently he's been wearing cologne, too and in my form (registration group), he sits in front of me and always turns around to talk to me, as well as taking my glasses case and hiding it so I have to talk to him to get it. Also, yesterday we left form and he stopped dead and only moved once I got pushed into him, as though he deliberately waited for it to happen. He also talks about his brother a lot, saying about how he has an English girlfriend (they're Albanian and I'm coincidentally English) and he "only" tells this to me about 20 times per hour. Also, recently his friends have been talking to me more often and I've become good friends with two of them.

Are my friends correct or is this coincidental?
