Today at work, Rob made a flourish in the air and asked how to describe the action. I had my trusty online Dictionary/Thesaurus at hand and quickly looked it up, only to find a wonderful new word: genuflect. Guaranteed I will forget it in a week or so, but right now I’m rolling it around on my brain and enjoying it’s newness.
