This is a test of commonsense. Complete the next sentence:

How to approach the guy you like
Make sure he knows who you are.
This is easy if you are already lab partners in science class or you work together in the same office. However, you may have a crush on a guy whom you've never actually talked to.
If this is the case, there are several ways you can let him know who you are without seeming like you're stalking him. If you have mutual friends, have one of them introduce you.
