Here is the difference, IMO.
My kids do everything on that list at our house. DS15 mows, DS10 helps. DD cleans the bathrooms. They all do dishes. They clean kitty litter, sweep/mop floors and help with the flowers/landscaping and do laundry, etc. I have no problem with my kids doing any of those chores on that list.
BUT - they do not do all of that stuff when visiting other people! Even for a week! And kids are not expected to do it when they come here.
I guess the reason I found it weird is because we often have our nieces and nephews stay with us - sometimes for the weekend for the in-town cousins, and sometimes for up to a few weeks for the out of state ones. After the age of about 6, I don't think I even had to tell them to put their dirty clothes in a pile- they just did it naturally. And when it came time to pitch in to help on a Saturday (when we do most of our deep-cleaning chores), we ALL do the chores as a family, so most of the time, the kid who is here just naturally starts to help with whatever chore the kid closest in age to him/her is. So, if my 17 year old nephew is here, and DS16 has to mow the lawn, nephew would go out and give him a hand. Or, if niece13 is here and DD12 has to clean the living room, niece will start picking stuff up, too. But they are not ASSIGNED chores that my family members themselves refuse to do for months at a time while they are off work. And there is no way, no how my husband would let one of our nieces get the lawnmower out and cut the grass while he sits around. He was brought up really old-fashioned - and he is NOT old-fashioned 99% of the time, but every once in a while little bits from his upbringing sneak through. Growing up, lawnmowing and taking out garbage was STRICTLY done by the boys in his family. It wouldn't sit right with him knowing he can do it himself and there is a 14 year old girl out there doing it instead. But along with that comes giving his seat up for a lady, holding doors, helping carry bags, etc, so I will take it
And. before we had kids, we have had our older nieces and nephews stay with us for weeks and weeks at a time when they were younger (tweens and teens) and we never made them do anything except hang out with us as we did stuff. Again, they would usually pitch in naturally - I have pictures of my now-30 and 29 year old nephew and niece with bunches of sticks in their hands when they, DH, and I were cleaning up the yard one summer. They were about 12/13 or so. I think that is totally fine and normal since they were with us for about a month. But if we took them for a week - no matter what the circumstance - I would never think to have them clean my house better than I would do it myself. It would be one thing if my house was immaculate all the time -
but in the case of co-worker and her sweaty selfie pictures of the background chaos in her home on a daily basis, I can assure you that these girls will do more cleaning this week than coworker and her husband do in a month.
That is what I think is weird!
I never make a kid do more work than I am willing to do myself. But that is just me. And trust me...my kids feel the farthest thing from "precious" there could possibly be.
