Your father has an assistant whom he used to torture. Soon the assistant learned to fly and even teleport. And his name was Zach, he was 26 years old. He is quite pleased with himself and happy, and since then he has not had a feeling of sadness. Today you were at school with your friends, and Zach had been flying after you for 4 days, although you were annoyed and tried to kick him out. He just looked at you smugly, not paying attention to your friends.
