Often times a woman will say something but I won't think of a good comeback until later. Here are some examples of some things to say in response to something she says about you:
Her: You are so sweet.
Me: I know. In fact you should put me in your next cup of tea.
Her: You are so nice.
Me: I am. But if you Take Away the "n" I'm really cold.
Her: You are really tall.
Me: Yep. But don't worry I won't look down your blouse. Or will I? You never know with me.
Her: Are you trying to pick me up?
Me: Well no because I have back problems. You seem like you might be just under my limit but I don't want to take the chance anyway.
