"In Praise of Wasting Time" by Alan Lightman, which reminds me of how #smallstories can be about paying attention. (some folks use the tag for short fiction, too, which I enjoy reading)
"My mind meandered." -- Lightman, page 4, as he remembers lost hours of his youth, just wandering the woods on his way home from school.
My blog is called Kevin's Meandering Mind, so this phrase jumped out at me.
