So today i'm on the way to class and I notice i'm walking next to an attractive girl, i'm just starting and all, but i've got myself psyched to know when I see a girl i'm interested in I just need to go over and say what's up instantly. So I turn and just say hi, she doesn't even look at me. I think she may have just not heard me so I greet her again; same result. In that moment I didn't know what to do as to not look desperate for her attention yet not seem like a total jerk, and then I turn around and notice a good friend of mine is just walking laughing at me; slightly embarrassing but whatever. So I just blew it off with him and stayed cool. So when/if this ever happens to you all, how do you generally react?
