If you have an interest then go ahead and ask him out. Dont wait or one day he's going to come in with a neck brace on from all the looking away. yes he likes you but hi most be shy, or scared that you are not going to take a chance of knowing so get a try at it and talk to him you dont have to be shy.but is he dosent like you you should ask him why is he always looking at you but he does like you.
