DSS is 16 and DSD is 12. We have them EOW and half the holidays. The only chore we ask is that they alternate loading the dishwasher and unloading it. So one day DSS does it and the other DSD does it. They feel this unreasonable and expect to do nothing to help. They leave their rooms an absolute pig sty. I just went to take out a baking tray and it's caked in cooked in food that wasn't cleaned off but just shoved in the dishwasher and then the drawer. I'm at the point of saying forget it and just do it all but DH thinks we should persevere.
