In the cake that is a happy marriage, secret gloating is a main ingredient. Unless the spouse is very dense, he/she appreciates what's not said and values his/her mate all the more. Sounds like PF knows the cake recipe "by heart."
I was very careful to not say a word when he told me they were too small and I did not offer to go get the larger ones. He started digging around for the zip ties, when he told me they worked fine I just said, "Good." No sense in rubbing salt in a wound...
