The truck driver, who left his dog in the cab and went away, was not at all happy when he returned.
It turned out that the naughty animal had locked itself inside the vehicle, so the man did not laugh at all. However, he still figured out how to solve the problem.
knocking on the glass, he managed to make the pet press the right button with his paws and open the window of the truck, after which it became possible to open the cabin. All's well that ends well.
