Some people quit when they are ahead.
I once baked the perfect challos. My husband went crazy over them, telling me that that are like from Gan Eden. I knew my challos would never be THAT good again – so I quit making challos, because you can’t get better than perfect and any other challos would be “disappointing”.
Some complements mean that the wife archived perfection in this thing. She will stop doing it because she does not want to disappoint with sub-par.
