A
I have completely forgotten the name of an old lady who was a customer on my paper route when I was a twelve-year-old boy in Marinette, Wisconsin back in 1954.
On a mindless Saturday afternoon, a friend and I were throwing rocks onto the roof of the old lady’s house in her backyard. The object of our play was to observe how the rocks changed to missiles as they rolled to the roofs’ edge and shot out into the yard like comets falling from the sky.
I found myself a perfectly smooth rock. The stone was too smooth, however, so it slipped from my hand as I let it go and headed straight for a small window on the old lady’s back porch. At the sound of fractured glass, we ran away very fast.
