Though shy guys will avoid actively pursuing whoever they’re interested in, they will often do things passively to show that they care. If he likes you, chances are he’ll be willing to take time out of whatever he’s doing to help you — sometimes over and over again. However, do not abuse your power over him. This is an especially cruel thing to do to a shy guy; in fact, maybe the reason he’s so shy in the first place is because he’s used to being treated badly.  Calmly and sweetly ask him to carry your books or your backpack for you to the next class. If you need an excuse (you don't, you can just ask him), tell him that your back is hurting you and you don't want to make it worse. Ask him to help you out with hard homework problems.
