This! With a house full of boys, beside the fact I wanted them to know how to do laundry. They all wore the same sizes eventually and I had no clue whose clothes were whose.
My Dh would happily point out I didn't know how to use a washer when we married

. We had crappy water in the house we moved to when I was about 11 so my Mom took everything to the laundrymat once a week so they would not get rust stains on them. Prior to that, she washed and ironed everything, even sheets and boxer shorts. She loves laundry and I LOVE when she visits now.
The boys are now self sufficient and tell the GF's the proper way to do laundry (learned from their Dad) of course! He says!
So now I need to go to the Budget Board and find outabout this crappy water heater we have, speaking of laundry
