They have

An ordinary autumn day. You were strolling peacefully through the city, sipping your caramel cappuccino. As you were crossing the street, you heard someone singing and playing the guitar. A cute young guy was performing on the street, collecting coins in his guitar case. You stopped to listen. The boy's voice was very pleasant, and he sang with a smile on his face despite the cold... Everything would have been fine, but suddenly some drunks approached the boy and started shouting:

—At your age, I was studying and working at a factory, and here you are singing songs!

The boy began to panic slightly and told them that it was "none of their business," to which the drunken men began to beat the innocent guy... What will you do?
