How do you tell if a man is flirting with you?

Im a girl so I kinda know how it happens. Its kinda easy to notice if a guy is flirting with you because they...

1. Blush when they talk

2. They talk to you constently.

3. He sneeks peeks at you during class.

4. His guy-friends say your name alot or mention you.

5. He complements you.

and lastly, he acts hyper when you talk about something. (Bulging eyes, constently moving, and he stops to talk to his 'neighbor', or a friend)

Hope that helped

I should know since I'm a boy. I will list them off. So, one sign is they may try to talk to you constantally. They may stare at you from across the room. Keep other boys out of a close radious. If they are very bold and not shy when they talk to you they if taller than you will look down at an angle while standing right in front of you.
