The best revenge, they say, is living well.
As you go to work, I’m breaking into your home. I intend to move your furniture into your roommates room, and his into yours. I will decorate your rooms such that it appears nothing has been changed.
I will move the furniture in your living room so it looks like the room was rotated 90 degrees clockwise.
I’ve already cleared this with your roommate, he’s going to behave as though your home has always been thus.
Living well may be the best revenge, but driving you mad will be a close second.
