On the way out of the dining room, I reached into the fruit bowl and selected a nice red winesap apple.
Later I took a big bite of "apple" and was shocked..."What's the matter with this apple?" It was wrong flavor, wrong color, wrong texture. Curious I took another bite. It was a NECTARINE.
It was a perfectly good Nectarine, only, I had expected apple. The shock came from expecting one thing and getting something different.
I was reminded of the time a dinner guest, unfamiliar with my Grandmother's cuisine, took a great spoonful of mayonnaise from the top of his Jello salad, and while I watched in amusement, put it in his mouth. He let out a yell as though he had been shot.
Since it was on Jello, he thought he was about to taste whipped cream, and instead got the tart bite of mayo. There is nothing wrong with mayo, except when you are expecting whipped cream.
