A little while ago, I worked out that a guy in my University tutorial group and I are both friends with some of the same people. I've only spoken to him once in the tutorial but we have been talking online over the break. He almost always initiates the conversations and has asked me how I'm finding my subjects, what music I'm into. Does it sound like he's interested in me or is he just friendly/bored? I have class with him tomorrow and I'm also not sure if, since we have been talking so much online, I should sit next to him or not....What are some body language signs to indicate he likes me?
