The man thought so little about the sentence “Laundry is the best job for a woman because it doesn’t require a lot of thinking” for 12 years that it only occurs to him that he’s been duped, not that he could have misunderstood the whole thing.

It’s possible the grandmother was saying “of the work that women tended to do (or that she did), laundry is the best one because it doesn’t require a lot of thought.”

My mom once told me her favorite job she ever had was working at a box factory because it didn’t require a lot of thought. And I was like “fair enough.”

This guy thinks so little he was angered into productivity for a dozen years.
