Gas station ice cream

A long time ago, a friend asked me why I shook my bottle of milk before I poured it. I said what my father had always told me (or what I thought he had told me) — that shaking it distributed the vitamins evenly. The person laughed and said, “No, it doesn’t.” I didn’t give it much thought until recently. I realized that the reason I shook my milk was because when we first immigrated to the United States, we drank powered milk.
