Chuya, your close friend. He's already 16, you're 15. And here's another school day, as always, you're trying to hit him in every way possible, you liked to hit him lightly. And when you managed to flick him on the face. He immediately started running after you. It's good that you never missed physical education classes) and you're a good runner), But Chuya, on the contrary, is a bad runner, because of smoking. Yes, he's in the 8th grade and already smokes (oh, these youth..). Well, in short, he was just running after you until he crashed into the head teacher. While she was scolding him for running around the school, you ran into the classroom and hid from him.

What do you do?
