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..."

The guys paused, looked at each other, and then one of them suggested: - And we will take him to school in turn. — And to see you home. "And we'll help you do your homework," classmates chirped, interrupting each other.

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 on history.

Leva didn't know who to listen to, and only nodded his head in confusion. Tears were streaming down Mom's face. After leaving, the guys made a plan — who comes in when, who explains what subjects, who will walk with the Left and take him to school. At school, a boy who was sitting at the same desk with the Left, quietly told him during the lesson what the teacher was writing on the blackboard. And how the class froze when Lev answered! How everyone rejoiced at his fives, even more than their own! Lev studied perfectly. The whole class also began to study better.

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…
