It's not just the difference between men and women - my MIL was like this. After eating, DH, FIL and BIL would enter the kitchen cautiously as it resembled a bomb site. The thought of the ghastly washing-up afterwards was almost enough to put them off the meal.
FIL excused the mess by saying that she learned to cook in the WRNS and therefore always had an 'underling' to whip away each spoon, say after use. Therefore why use one spoon it you can get away with six? MIL's belief was that the cook didn't wash up.
I was taught at school to clean up as you go along. She thought that I was daft.
