This is a tale I found online

There was a little boy whose mother was about to have a baby. One day, the little boy walked in and saw his mother naked. He asked his mother what the hair between her legs was.

She responded, "It's my wash cloth."

Weeks later, after the mother had her baby, the young boy walked in on his mother again. While she was in the hospital the doctor had shaved her pubic hair.

The boy asked, "What happened to your wash cloth?"

The mother responded, "I lost it."

The little boy, trying to be helpful, set out to find his mother's washcloth.

A few days later, he ran to his mother yelling and screaming, "I found your washcloth."

The mother, thinking that the child was just playing, went along with the boy and asked, "Where did you find it?"

The boy answered, "The maid has it! She is washing Daddy's face with it."
