As a student, she worked as a salesman in a store of products for sewing and handicrafting. Somewhere nearby lived a madman who was bored, and he was entertained by shop scandals. It was not officially the first. He usually came and started asking stupid questions until either the seller came out of his hand or the buyers in line. After that, with a clear conscience, he arranged hysteria with screams, whispers and matts.

One day he appeared again and began a conversation with the question: "Why is this round red button with a diameter of 20 mm different from this round red button with a diameter of 40 mm?"

There was a new woman in the room who had never met him before. She looked at him with honest eyes and answered with a clear voice: “The difference is in diameter, one 20 mm, the other 40!”

“You, girl, a programmer, probably,” said our favorite and disappeared for a couple of months.
