guys I'm wondering what signs do you give a girl you have a crush on. I see this guy at school who always looks at me when we come into contact with each other but we never spoke I always thought he had a crush on me from other clues I got. But I'm wondering do guys go out there way to see there crush. What do you guys do would you go out of your way? would you go out Ur way to see a girl you like or would you just wait till you see her if you run into her?
