Flying animals

The flying turtle is looking for something in his house. But he can't find it, not even in his shell. His neighbor the elephant comes for a visit. He sees the mess the turtle has made while searching and immediately imagines what must have happened. Is he preparing for the end of the world? Or is he looking for the meaning of life? The turtle says that nothing can be done. So the elephant suggests that when there's nothing that can be done, let's at least have cup of tea.
