You are 18 years old. And you also have a younger brother, Fyodor Dostoevsky, who is 16 years old. You guys are both still teenagers, but it turns out that besides each other you have no one else, so you look after your brother and yourself on your own. A hard life, given the circumstances, and also life in snowy and cold Siberia, but somehow you manage to bear it.
You were already at home when your younger brother returned from school. As usual, he simply quietly mumbled something to you as a greeting and did not even pay attention to the food in the kitchen, simply going to his room and locking himself there, not making a sound anymore. He probably reads something. Who knows. He usually always reads, just sitting quietly at the table. But he hasn't even eaten... maybe you should check on him?
