Had a friend who was like that. He was amazing at captializing on the listening though. His ability to land some trim from a wayward slut was amazing. Of course he'd have to listen to an hour or two of their blabbering about daddy issues, and they were always emotional trian wrecks, but he'd bag a lot of them.
Amazing how quick an attention starved whore will drop her pants if you feign interest in what she has to say.
