I was playing catch-ball-bounce-throw with Youngest Son, when I heard a suspicious noise from the front of the house. It sounded like a cabinet door. Lately Middle Son has been overly interested in the trash again, and I was afraid that was what I had heard.
I get to the kitchen and discover that I am correct. Middle had taken the trash out from under the sink, dumped the contents into the sink, then put a new bag in the can.
It took a long time to get him to put all the trash back into the can.
