Housework was a woman's job.

[LegalAlien]

Housework was a woman's job, but one evening, Jenny arrived home
from work to find the children bathed, one load of laundry in the
washer and another in the dryer. Dinner was on the stove, and the
table set. She was astonished! It turns out that Ralph had read an
article that said wives who work full-time and had to do their own
housework were too tired to have sex.
The night went well and the next day, she told her office friends
all about it. "We had a great dinner. Ralph even cleaned up. He
helped the kids do their homework, folded all the laundry and put
it away. I really enjoyed the evening."
"But what about afterward?" asked her friends.
"Oh, that ..., Ralph was too tired.."
