There are surely exagerations and strange behaviour but in this case it could only mean one thing: he has a lazy wife.
I am not a lazy wife and my husband does the laundry in our house. I cook dinner, pack our lunch for the next day at work, he cleans the table after dinner and starts the dishwasher, we both clean the house on the week end, I iron and he does laundry. Neither of us i lazy and he doesn't certainly sends the laundry to his mother's to be done.
It's called SHARING, and taking care of each other, that's what marriage SHOULD be about. I think.
