I've come back to where I parked my truck. Another truck, a newer blue one, is parked very close to it, so close I think they might have collided. But on closer inspection, no, they are just very close.

Then I notice that my tires are wrong. They're all worn down to small donuts, barely enough to ride on. I'm pondering this when a girl comes by, looking for her tires which apparently rolled away. They are the worn-out ones, and my tires are fine.
