I go to my daughter & son in law's home to dog sit while they go on holiday ... I say to my daughter I will get you washing up straight, which I do ... yes very grateful, may I add no ironing !!! I wash it dry it fold it , I never go in their drawers to put things away ... I usually put it in their spare room folded ... if I tidy up the table I make sure everything left on there, but tidier, maybe in a corner ... yes vacuum & tidy up the lounge, kitchen, etc rooms I use ... they have a cleaner once a week. My daughter & son in law are grateful. When my husband was alive, he would vacuum & do the disher washer etc ... & mow the grass when they had lawn ... this caused no problem what so ever. I would never ever move things as such. What if she moved something important ... is she really that forgetful I wonder or just wanting things how she wants them . If she wants to do things get her to bring her own things to do , or even start a jigsaw / wasgig then say something like, I have started this so you can carry on ... she hasn't any right to mess or move things in your home !
