Maybe it’s a matter of different family traditions. Since childhood, the husband has used to keeping the peelings in the broth so that they do not cling to the shell, and the wife - that they do not hold, so that they do not scatter. Tradition is almost a conditional reflex, which is very difficult to survive, and when it is frankly harmful - it works on the machine. I heard the story of a couple where each other’s nerves were crushed, as the spouse A (I don’t remember which one on the floor) pressed the toothpaste in the middle, and the second wanted (for some reason in principle) to be carefully pressed out and bended from the tail.
