gooorls-Changing a no to a yes?

[gamblore99]

The other day I asked a girl out and she gave me a "I dunno..." type response. I took this as a no and told her I would talk to her later, which I didn't really plan on doing.

My friend says this is very common, and I should be able to get past this and turn the answer into a yes. He says this kind of thing happens to him a decent amount, and he usually teases them a little, makes it seem like they are hitting on him and then brings it up again.

Discuss.
