Yep, I am this many years old...
I distinctly recall milk home delivery from our local dairy, "Twin Pines." I remember how my sister and I would race down the stairs first thing after waking up to be one who got to open the milk chute* and discover the frosty cold glass bottles of milk and sometimes a tub of fresh cottage cheese too if our mother was dieting.
I am always remembering...
*For the younger readers of this, a milk chute, or provisions cabinet is an insulated box built into the wall of many mid-century homes. It has a door outside the home accessible to the milkman and a door inside for the homemaker to retrieve the goods delivered fresh to her home that morning. Now you know what that strange little door located near the kitchen on the outside of many homes was for. We had home delivered milk until sometime in the early 1970s, afterwards we bought our milk from the A&P (a story for another time).
