It's a good system that works for us
That's the key thing.
After 31 years of marriage my DH and I know whose job is what.
I probably *could* change the propane tank on the grill if I had no choice, but those tanks are just a bit out of my weight range so he changes them and is teaching the almost 15yo DS#3, who is taller than his father already.
He *could* patch dings in the plaster but he's not got the patience for fiddly work so just like I have heavy chores done by telling him they're needed he gets fiddly stuff done by telling me it's needed.
