M seems depressed. He doesn’t enjoy talking.
When being involved in a conversation unconsciously, he closes his eyes, imagining he is a 🐳 in the deep sea.
Meaningless sentences hit his tympanic membrane. M, now a 🐳, considers them water flow. He feels their existence, but couldn’t care less.
When a 🐳 gets tired of the tranquil lifestyle underwater, it jumps out of water. So does M.
M jumps out of the water.
