On the bus, a little boy was kicking the seat in front of him and disturbing the other passengers, while his mother was busy with her phone: but suddenly one of the passengers did something unexpected 

On the bus sat a mother and her young son. As soon as they took their seats, the woman pulled out her phone, put on her headphones, and got absorbed in a TV series. She paid no attention at all to the fact that her son was causing chaos: he laughed loudly, pulled at his mother’s arm, sang, and kicked the seat in front of him with all his strength.

Everyone disliked the behavior of the ill-mannered boy, but they tried to stay calm.

One of the passengers couldn’t stand it anymore and said loudly:
— Control your child, he’s disturbing everyone.

But the mother calmly took off one earbud, looked at him, and replied:
— That’s none of your business. I don’t forbid my son anything. He’s a free person.

Then she put her headphones back on and returned to her screen.

The boy continued to misbehave, annoying everyone, and kicked the seat even harder. When he saw that people were getting angry, he only laughed louder, as if he enjoyed the scene.

But then one of the passengers did something completely unexpected, after which both the mother and the child deeply regretted their behavior  Continued in the first comment 

One of the women decided to act differently. She turned around and started kicking the seat where the boy was sitting.

The boy cried out in surprise:
— Ouch! Stop, it hurts!

But the woman didn’t stop. The boy began to cry, and only then did the mother notice what was happening. Taking off her headphones, she turned sharply and shouted:
— What are you doing?!

The passenger looked at her coldly and said:
— My mother never forbade me anything either. I can do whatever I want.

The bus fell silent. For the first time, the mother thought about how her own words sounded to others.
