Remember the milkman?

Remember the milkman? Ours came early in the morning, and the glass bottles would be waiting in a box by the back door before we were up. If you needed something extra, you left a note tucked in an empty bottle. In the winter, when it got cold enough, the cream would freeze and push the little cap right up off the top. You could hear the bottles clinking when he set them down. I haven't heard that sound in a long time, but I'd know it anywhere.
