Yeah, I did that with my best friend as well.. and the story always went in a completely different direction for some reason. When I would think that it would be simple and just go forward in a normal way, she'd throw in a twist and all of a sudden someone is pregnent or out in the desert meeting the mafia for some kind of secret deal... honestly though, it made it a lot more intresting and unpredictable. Then, if she messed up an idea that I thought would be cool with a twist, if I saw that she was going for something borring, I'd throw my own twist in there to throw her off as well XD
