again, main emphasis is on it being someone you know
the reason pochita messed up when he asked a bitch at the mall out was due to him not knowing anything about the person. if you really want someone to like you, you gotta try to get to know them, see if you both got common interests, talk about family hear and there, etc.
only then will you get a chance of succeeding. its a long trek, but it ensures you good odds
