Last week, Julie and I drove to our favorite nursery — which I call the grass and tree place — to pick up some Calliope plants to block the neighbor's view of our garage door. Notice how I used flower and grass language because my wife doesn't think I have any idea what the difference is between flowers and grasses. Also notice I did not show off my extensive knowledge of the Calvin cycle of enzyme-catalyzed photosynthesis occurring in chloroplasts and other stuff.
