What do you say back to your such a charmer when the girl says what brought you to my home today then you say just to talk to a freaking gorgeous girl like you then she says why your a charmer?

you say your glad she thinks so. You should compliment her once or twice after this. You need to make sure she knows you are honestly interested in her. So you should make it obvious.

If you like to be mysterious, you should say you were just passing by and decided to say hello. Then you say you have to go and leave her guessing. You turn and start to walk away and then you turn around and say say something like "your hair looks nice today". It will excite her.
