Tsh. Tsh. Tsh. – each step of the teacher’s shoe echoes like a gong in his ears, but the sandman slows his heartbeat so that it cannot be heard from the outside. Catching glimpses of clothing fragments through the micro-cracks of the shelter, hinting at certain death, he tries to merge with the ground as much as physically and mentally possible. It seems that if you look him in the face, he will detect you, just like a monster from a nightmare, so the guy is grateful to the embrasure for its limitations.
