I've found a little bit of success recently in saying very little/not opening up and letting the girl do all of the talking. I feel like I have some interesting things to say and funny responses, but even when these lines make her laugh or my stories engage her, it seems like the more I say, the less attracted the girl becomes (body language becomes weaker, she starts opening up less, etc.)

It's weird because by not talking, I feel like I'm showing zero personality, but it somehow works. Is this accurate? Should I talk less around girls I'm trying to seduce than around normal people?
