I have 1DD 21 and 1DS 19. From birth, I chose to work part time and take on all home chores, while my husband put a lot of hours into his job. For efficiency, I foolishly did the same for kids. Now they’re fully grown, living at home and leaving my kitchen a mess 3 times a day, not clearing up after themselves. I come in from work planning to cook dinner, and there’s not a clean work surface or pot in the house! I’m the kind of person who couldn’t cook while all mess still around from last cook, not to mention no clean utensils. I’ve threatened not to cook if the area isn’t clean, but then I’m throwing uncooked ingredients away. They’re both still in full time education with part time jobs, so I don’t charge any rent etc. Obviously I keep telling them, but they aren’t bothered. Boy far worse than girl. Can anyone suggest a strategy that might be effective?
