Strike Up a Classroom Convo
If you happen to be sitting next to the cutest boy in class, here's a trick to get his attention:
Try to drop a pencil or paper near him and ask him to pick it up for you. That way you can get a conversation started. Or, if you have time after class before the bell rings you could try staying, "Did you get the homework? Because I couldn't hear him (or her)?" Good luck!
