So that happened.

 So that happened. She had been flirty, for sure, and fun, and he followed her home.

 And then she had made this crazy joke... like.. "Why don't we switch places? I live your life, and you live mine. How hard can it be to be a stock broker, yeah? And I am sure you can manage to be a bartender. I mean, there are books about making drinks and stuff."

And he, thinking she was joking, agreed. Then she cut his finger and then she cut her own, and then she mixed their drops of blood and said some stuff in a weird language. And then he watched her leave the flat with his body. "Don't bother to call me!" she said.

He guessed this was his flat now.
