With a voice from beyond the grave, the shadow explained to a body sitting on the bench:
-I do not exist, only you exist, thinking mind wrapped in a skeletal body.
The cry of a child woke him from his reverie.
He continued reading the letter:
-Goodbye, John. I am tired of being your shadow. 25 years. Any future lectures, I will make them from my own philosophy of life. I will deny your existence. Kisses.
John stood up, but on the third step, he turned back to the bench.
The shadow still sat there, staring at him with vacant eyes.
Suddenly, it pounced on him like a thirsty creature.
John screamed as the dark entity devoured him, taking over his mind and body.
In the end, only the shadow remained, free at last from its imprisoned existence.
