Do you think he likes me?

He's in my homeroom and sometimes I see him stare at me a lot and I laugh at all his jokes, he's also in my other cl and he sat next to me a couple of times but we didn't talk and he also sat next to me when where on the computer, he plays lacrosse/football and he is really smart, whenever I see him in the hall way he still looks at me a lot when where not in cl and also the theirs a bookshelf in the clroom so he looked over it and smiled at me
