I've used this a few times and it works spectacularly. Instead of giving the HB something of yours, take something of hers (sunglasses, bracelet et cetera) Then walk away and tell her you will give it to her by the time she leaves you just want to play with it a bit. This puts you on her mind constantly, she will be trying all night to not forget that you have it and for that simple reason you will not leave her mind all night. The only downfall to this is that you need to build up a little trust before taking something of hers. You can even number close before you give it back by saying "If you can't find me before you leave to give it back, here's my number" I don't recomend it though it is kind of forcing her to give you her number. Then when you give it back later on you can DHV with something like " Thank you a million, I picked up so many chicks using this. The damn thing works wonders with women (give a joking smile)" Then just simply continue your game.
