Husband Conspires to Drive Me Insane

So, this afternoon I said to the hubby (who was laying on the bed with The Little Dude) 'I'm going out to get something to eat. Coralie is downstairs in the family room'. I went to eat and was gone for about an hour. When I came home, I noticed that she wasn't in the family room... or in her bedroom... or in the nursery... she was in the master bathroom, with the door closed. PLAYING IN THE TOILET. My husband had slept, and left her COMPLETELY UNSUPERVISED FOR AN HOUR. Fortunately the damage was limited to drawing on the desk, leaving a marker with the cap off on the couch, and a daughter and bathroom soaked with toilet water. Imagine what would've happened if she was *really* destructive. His response? "Oh, I thought she was with you." I thought my head was going to explode.
