Dear last and final former-would-be-housemate,

Game theory suggests that I should take the next available opportunity to shaft you for having thrown zeightyfiv and myself under the bus for your own convenience, particularly at this late a time. But I'm so disgusted by your behavior that I'd just be happy to never see you again. (I realize that this may pose a problem if you see the error of your ways and respond to zeightyfiv's e-mail appropriately, but I'll deal with that if and when we come to it.)

No love,
- Me
