One afternoon, a mother decided to wash her hair and put it in rollers before getting ready for the evening. She searched through the bathroom cabinet for a hair net, but couldn’t find one anywhere.

After a moment of improvising, she grabbed a clean pair of panties and stretched them over the rollers to keep everything in place.

Her four-year-old son had been watching the entire process with wide, fascinated eyes.

His mother noticed him staring and laughed.

“Don’t look so surprised,” she said. “It’s just to hold my hair. Good thing it’s only us at home, so nobody sees me looking like this.”

The little boy nodded very seriously, as if he had just learned an important grown-up secret.

Just then, the doorbell rang.

Before his mother could react, the boy ran down the hallway and opened the door.

Standing outside was a salesman with a briefcase and a big polite smile.

“Hello there,” the man said. “Is the lady of the house available?”

The boy turned around and shouted at the top of his lungs:

“Mom! Mom! Take off your panties! There’s a man here who wants to talk to you!”
