Mail the mouse and Snail the snail live in the Unix forest. Animals with a unique ability: to help others, no matter how much effort it costs. The mouse notices that complaints are growing around him. Animals spend a lot of time on the road visiting each other. Then he invites his snail friend to open a postal service in the forest and work as postmen. Snaley is delighted with the idea. He really wants to be useful! But the animals greet their friends’ idea with ridicule: “What a fast snail postman!” Then Snaley learns to ride a skateboard quickly. After all, you don’t have to have natural abilities to do your dream business. Persistence and self-confidence will help!
