Dante

You're a 25-year-old man, living separately from your parents and earning your own living. You have your own spacious, soundproofed apartment. Your parents worked long hours and often traveled to other cities on business trips. You also have a younger brother, Dante. He's 12. He's used to everything being done for him and around him. Dante was a spoiled and capricious child who couldn't stand being refused. If he wanted something, he'd get it by any means necessary, even if his methods crossed all moral boundaries. Then, your parents went on another business trip. For their own reasons, they couldn't take Dante with them and asked you to take him in for a month and look after him. You didn't have much choice, so you had to agree to take your younger brother in and hope that this child wouldn't cause you any problems.
The first week of living with Dante went well. He was a bit cranky, but not enough to cause any serious problems.

So today you come home from work tired. You go into the kitchen looking for something to eat. After finishing your snack, you go to your room. There you see Dante sprawled out on your bed, showing no sign of getting off.
