This is most definitely not a MIL bash - as MILs go mine is great. As a retired home economist, and the possessor of a show-home-standard house, I tend to defer to her expertise in most things domestic. But she does something that I can't make head or tail of.
On a few occasions when she's dog- or DC-sat for us, there's been a laundry going. Rather than just leave it where it is until I get home to deal with it, she takes it all out when it's finished, partly folds it and puts it on the work top, stacked up. She once folded an entire load of sheets straight out of the washing machine. As we didn't get home until the following day, the exposed bits of the sheets dried completely, such that I thought they were dry and almost put them away. It was only when I wondered why the sheets felt particularly heavy, that I slid my hand into the middle and realised they were still completely wet.
I hasten to add - I have never asked her to deal with our laundry and never would. She has just noticed it was there and taken it upon herself to do this strange thing that I can't grasp the logic of. She could put it in the dryer which is in plain sight, but she may think we're selective about what goes in there, so I get that, but why not just leave it in the washer? Why stack it in a folded pile to get stinky? I'm too shy to ask her why she does it because I know she's being helpful and I don't want her to think I'm having a go when she's usually already doing us a huge favour by babysitting. I've asked DH why she does it, but he has no idea.
Do any of you domestic goddesses know?
