Two little children, a boy and a girl, walked hand-in-hand to a neighbor's house.

The little girl stood on her tiptoes and just able to reach the doorbell. Then, an elderly lady greeted them at the front door.

"Good morning, children," she said. "What can I do for you?"

"We're playing house," the little girl answered. "This is my husband"... "and I'm his wife. Can we come in?"

Thoroughly enchanted by the scene, the elderly lady replied, "By all means, do come in."

Once inside, she offered the children lemonade and cookies, which they graciously accepted. When a second tall glass of lemonade was offered, the little girl politely declined.

"No thank you," she said. "We have to go now. My husband just wet his pants."
