In the line at the box, Magnet. My son and I (4 years old). In front of us in the line a guy rocks the phone and cries out loudly, "Fuck me!"

My son pulls my hand: Daddy, is this uncle stupid?

I: Why do you think he’s stupid?

Son: He says bad words that cannot be said!

The line is listening, I explain that uncle is just upset, and the words are not bad, ordinary.

Son: No, such words cannot be said! If he was upset, he could say something else.

I: Which of them, for example?

My son, for instance, is your son.
