I had a weekend job as a caricature artist at the Gaylord Hotel in Nashville, TN. I had a girl with glasses sit down to be drawn. I started stroking in some lines and she decided that she didn't want be drawn with her glasses so she took them off and held them in her hand. The glasses slipped from her hand and made a 'clack' sound on the concrete floor. Even though it was kind of dark, my stand had lights and I could see her glasses out of the corner of my eye laying there at her feet. So I finished drawing her and then she reached down to get her glasses.... but they were gone. The girl, her friends and I all got down on our hand and knees looking for her glasses. I disconnected the lights from my stand looking for the 'glint' of her spectacles but we never found them. She gave up and shrugged like it was only another visit to the Vision Center for her. Even after she left, I looked for them but they were gone. And they were gone for good. Where could they have gone? Did they phase into a parallel universe like all of those socks that get lost in the laundry? Or did they lose their 'molecular cohesion' (this happens on Star Trek frequently) and dissolve into space? WOW! The mind reels!
