I have large quantities of these small, pale, flat-ish stones. Perhaps they have a name; if so, I don’t know it. My grandchildren would call them skipping stones, as their shape is good for bouncing over the surface of the water. I call them worry stones. I often have at least one in my pocket. When stress, nervousness or worry want to take hold, it’s good to have a bit of nature to grab on to, for support.
