When he learned that his time had come, he decided to write his epitaph. To be remembered by in the place where he had always lived, to capture a nice thought or just to say goodbye. He wanted to leave something.
He needed it. As a kind of consolation, in the face of his imminent departure.
He did not know what awaited him there, on the other side. No matter how many legends or stories he knew, the fact of starting his final journey without knowing his destination terrified him.
At last he came up with the exact phrase and only then did he feel he could leave. At ease, light luggage, no pending debts. He closed his eyes, and after those nine months that seemed eternal, he was born.
