A few years ago, we were desperately trying to sell our house, which was situated on a busy thoroughfare. Our real estate agent decided to have open house inspection nearly every day to promote the sale. We instructed the children not to talk to anyone about the house.
One evening, a man took our seven-year-old daughter aside and asked if our house had any secrets he should know about. Her first reaction was to smile and ignore his question. But he became more persistent and, finally, she confessed there was one secret, but she could not tell him.
"Now we're getting somewhere," he said. "Tell me the secret. I promise I won't tell anyone."
She looked him straight in the eye and whispered, "We have monsters in our sewer."
