My hands would not tolerate this sudden vacuum, so I picked up my wife's camera. A camera-shy Donna covered her head with the napkin. I wish I could show you the shot I took of her hiding... under a napkin! It was a comical paper babushka..
Later, someone whipped the napkin back at me, so I played with it even more, until it rested on the table. Fatigued from all the previous activity, it lay very, very still. Carefully then, I picked up the camera. Here is the photo. It looks like it was impersonating a head of lettuce; what do you think?
