Most people are not well acquainted with the tops of their heads.

They don’t make top-of-head mirrors. They would have to be quite intricate, and bulky, and cumbersome. And most people only look at the front, anyway. Not me.

In fact there’s not much that can go that wrong with the top of one’s head. I watch the crowds of people zig-zagging across the square below, each diagonal in the wind, flip-flopping like blades of grass in a sandstone meadow as the gusts dance and change direction. And as I look down at those hairy or hairless or hand-clutched-hat-covered scalps, not once do I see someone and think, you ought to buy a head mirror, mate.
