When is Samuel coming?

Two men are waiting by a swing for Samuel's arrival to celebrate a party. To overcome boredom, they invent games, they imagine. Mr. Teacher comes, gives them the lesson and leaves.  

One is a man looking at the moon. 

Another is a man who embraces the earth. 

Mister Teacher is a man who throws words into the air. 

The moon and the sun play spending time. They wait for each other. They never meet. 

A swing, at last, a wonderful toy, a trampoline, invites us to fly.
