Zima came by for a hike last night. Early in the hike a truck passed us on
the road and a dog in the truck barked loudly at us. Zima started to chase
the truck, but eventually it got away. But Zima must have believed that the
truck and the dog were the same thing. So, for the rest of the hike Zima
attacked every truck that passed, thinking it was her enemy. Even trucks
that were parked got a good going over. But in the attacks she was almost
run over several times.

Moral: Mistaking the vehicle for the dog can be very dangerous.
