"It's Rumoured that man suffers so deeply that he had to invent laughter."
"I laughed so loud yesterday."
"How could you be so sad?"
"Life is a thousand times too short; I wanted myself to spin like a ballerina, but it turned up I visualized myself only as a fat top."
"That's a bad reason to laugh."
This creative visualization, in mushroom's terms, is called little daydreams.
