Make a tiny complement to him. You don't have to say something that may be too direct, like telling him he has good eyes, or that might make him flush too much. However, noting something he's skilled at or something he's wearing may draw his attention to you. Don't go too far. He'll think you're trying to hit on him. Do something active with him. If you both like sports, go for a game of soccer. If you both like movies, check out some together. The more you two do together, the less likely it is that he'll see you as a parent figure who can't be compared to other men. Be a friend. Boys your age are often looking for friends. If you give him your phone number and go out for ice cream once in a while, he won't think you're weird for wanting to be his girlfriend. Here are some other ideas: play music together, watch TV shows or movies together, talk about your days, etc. But mostly, just be a friend.
