An amazing story about the boy Lev

A story that all of us should know.

In one Moscow school, a boy stopped going to classes. He doesn't go for a week, two... Leva didn't have a phone, and classmates, on the advice of the teacher, decided to go to his house. Levin's mother opened the door. Her face was very sad. The guys greeted each other and timidly asked: "Why doesn't Lev go to school?" My mother sadly replied: "He won't study with you anymore. He had an operation. Unsuccessful. Leva is blind and can't walk himself..."

Tears welled up in Mom's eyes. She led her friends into the room. A little later, feeling the way with his hand, Leva came out to them with a blindfold over his eyes. The guys froze. Only now did they truly understand what misfortune had happened to their friend.

Leva said with difficulty:- Hello.

And then from all sides it rained down:- I'll come for you tomorrow and take you to school.— And I'll tell you what we did in algebra.- And I'm in history.

Lev Pontryagin 's parents are Semyon Akimovich and Tatiana Andreevna Pontryagin

In order to explain a lesson to a friend in trouble, you need to know it yourself. And the guys tried. Moreover, in winter they began to take Leva to the skating rink. The boy was very fond of classical music, and classmates went with him to symphony concerts…
