This morning, as I reported on Twitter, I woke up to a phone call from my wife that it was raining in the kitchen. It turned out the same loose tank connection allowed water to leak from one of the upstairs bathrooms. The water seeped behind the baseboard, through the wall, and onto the ceiling drywall in the kitchen.
All of this was discovered by The Fuzzy Headed Oracle who, upon waking up and beginning her morning routine of walking through the house, entered the kitchen, noticed the wet floor, and finally got to use her new favorite word in the proper context:
"Uh-Oh"
