My almost 35-year old stepson moved in with us following the end of his engagement. We're not asking for rent or grocery money. We asked one thing of him: pick up after yourself.
Every day, we come home to dirty dishes and empty food containers on the kitchen counter, dining table, end table in the living room and in the office. He even gets up from meals and leaves his plate there while we're cleaning up. And no, we don't clear his plate.
We've repeatedly reminded him of our one request. Some of the dishes have at least made it to the sink. But not the dishwasher. Ugh.
