Apparently the one bag I had made wasn't enough. They put this one in without taking the plastic off. Thankfully one of them had the smarts to shut it off when it started to "smell like when daddy changes the oil".
The picture doesn't do it justice, there is melted plastic all over that old man's face.
"We cleaned up for you" - and they did! And the astonishing part of this is that things were actually all put where they belonged, not just tossed in a pile somewhere.
You should try leaving your 4 and 5 year old completely unattended for an hour and a half and see what happens. Either they'll burn down your house or clean it. I was lucky with the latter. This time, anyway.
