These are my friends Smarty and Ben. They’re rescue greyhounds sharing a domecile with my boss Gianna and her husband, the gent at the other end of the leashes. When Gianna’s family goes on vacation, I sometimes see my friends Smarty and Ben out walking with other humans. Usually I recognize the dogs first. Once Smarty walked up to me in town and mentioned he liked my shoes. I thanked him before I realized I was talking to a dog who would never need shoes, and that was some incredible abstract thinking on his part.
