A Study of Perpetual Motion

I'm not sure how it started. Swing, swing, swing, back and forth. Quietly, I block the small limb with my leg. The other one starts now: swing, swing, swing, back and forth. I block it with my leg again. Almost as if on cue, rub, rub, rub, his little head against the back of the pew. I give him a nudge. Then the bottom--scoot, scoot, scoot, rock, rock, rock. I finally lean over, eyes still closed (because we're supposed to be praying) and say, "Can't you please just sit still?" Bear looks at me and smiles. He's still for about, say, a nanosecond. Then the leg starts again......A body in motion stays in motion.
