Ask a guy out: I don't know why asking a guy out should be such a complicated scarification ritual..You just walk up to him, and start talking. Try to get to know him better, ya? Then, when 你 feel comfortable about it, ask him out. If he's interested he'll say yes, if he's not then he'll say no. It's THAT simple.

It's THAT si-- *gets shot 由 a million of people who actually have experience*
