An easy way to tell a boy that you like him would be by first finding out whether he likes you first. This you can find out from his friends and the relationship between the two of you. Once you have established this, you can get confident and bravely tell him that you want to have some time with him away from his friends. As you tell him this, be confident about it. You can also choose to write him a note telling him that you like him and stick it to his locker. Get more tips from http://www.wikihow.com/Tell-a-Guy-You-Like-Him.
