I'll get to the lesson shortly. First, I'm going to bore entertain you with a story. While helping my 77-year-old mother clean out her closet the other day, I got the jobs of climbing the stepladder and moving the heavy stuff. I also got the job — when her vacuum attachment didn't fit — of laying on top of a jumbo Spacebag to press out all the air. She wanted the bag smaller, so she joined me. There we were, side by side, flat of our bellies on this thing and sprawled across her bed. It was a Kodak moment. (Not.)
