As a child and teenager, I loved milk. Whole milk.
When I was very young, a milkman delivered to our house, twice a week. We got the pasteurized milk in glass bottles with green tops, while my aunt & uncle next door got homogenized milk with red tops. That meant at our house there was always an inch or so of cream at the top of the bottle, and no matter how much I shook the bottle to blend the cream into the rest of the milk, there were disgusting thick white clumps on my Alpha-Bits in the morning.
As a teenager, we got milk in waxed cardboard cartons from the supermarket. Homogenized, thank you G*d. My mom always had warm-from-the-oven homemade cookies waiting for us when we got off the school bus late afternoon. A tall glass of cold milk was the perfect accompaniment.
Then I moved out on my own. With room mates.
See that stove?
An antique Norge. Best stove I ever had. Pilot light. Kept the whole top of the stove warm. Great spot for raising bread dough. Bad spot for a room mate to leave the milk. All day. A second room mate would come home, see the milk on the stove and put it back in the refrigerator. I would come home and pour myself a glass of . . . clumps. Made those clots of cream from my pre-homogenized day seem almost palatable.
Which is why I can no longer drink a glass of milk.
