@Nimis: Your story reminded me of a similar one in my family. Before the days of automatic ice makers in refrigerators, we had a family problem of reaching in, only to find an empty ice cube try, or maybe one or two cubes left. We also had 6 in the household, and my mom would always yell at the kids to stop doing that and refill the tray. One by one, we all went off to college and the problem still persisted. I was the last one at home and alone for nearly two years, so I was constantly blamed.
I then went off to college, and my parents moved to Hawaii. The fridge still had no ice maker, and the problem continued. The first break, I come home and lo and behold, one has been specially installed. It was a gift from my dad to my mom. He had finally been caught. He had never denied it, because she never blamed him.
