"A Fair Swap"

I read "A Fair Swap". I read the story like this.
There is a parent. Husband always goes to work and wife works in their home. One day, husband said, "Let's swap the work each other!". So wife accepted this proposal and different life began. This life could not succeed. Husband couldn't do his given work. He failed all his work.
Fainally, he acknowledged that he was wrong and his work fits him. Then they return their life until now.
