The Little Goat and His Grief (1976)

The authors of the animation film tell us about two very close friends - a Goat and a Donkey. Once they were overtaken by misfortune: playing with a balloon, they burst it. The grief was so great that the Goat collected it in a huge bag and went into the forest. On the way, he shared his misfortune with all the others, and by the end of the journey he had nothing left.
