When Mabel Watson Payne got home from Huntington Playground with me on Friday it was almost 6 p.m. and her mother was already home from the office. Mabel reminded me to unzip the compartment in my jacket where she had deposited all the treasures she had collected from the bounty of the Earth (and consigned to my keeping) during the course of our outing, Then she assembled them on the palm of my hand while we explained their individual significance to her parents. And my daughter whipped out her trusty phone and recorded their beautiful (though momentary) propinquity.
