Brandon stepped down to investigate, and found a large corner of the carpet by the bookshelves soaking also. The wet area was quite large, and we could find no source for the water. It wasn't likely to be seeping up out of the floor.
With no visible source, we quizzed the girls. Did either know what happened? Kathleen immediately claimed no part in the problem, but pointed the finger to her younger sister. Sophia, happy to claim the blame, admitted that yes, she had gotten the carpet wet. We asked her how, but she wasn't talking.
With a stern lecture about not putting water on carpets (thank heaven for stone floors), we put a fan on the spot, and finished cleaning up dinner. Sometime during the events, Sophia solved the mystery by explaining that she had wet the carpet with her watering can so that she could wash it. We explained that watering cans are only for watering plants, and thought nothing more of it.
Until Sunday morning, when I found the carpet wet, again. This time, there was a definite trail - from the wall. I checked the air conditioning closet to find 1 1/2 inches of water on the floor. After facilities came to check it out, there was only a drainage hose askew.
The next time I need a ready confession, I'll just ask Sophia for one. Not only is she willing, but she's creative, too
