Might I add that also, we're afraid of suddenly, if we ask you out, being regarded as a creep guy... Eg: "I was just being friendly w/ Joe, then he tried to ask me out, and that's just creepy, ewww..."...

I know that's the sum of all the fears I have about asking a girl I like out, and if it's a shy girl who doesn't really give me a good feeling, like that's not going to happen, I'm not gonna make a move, for fear it will :/
