I recently bemoaned my inability to comprehend the movement of objects in space. Any kind of space. The phases of the moon continue to mystify me even though I’ve seen that fat sucker roll around (predictably, according to experts) some 850 times. I have no idea where a ball I’m throwing is going to go. In the space between my ears, I can’t fold up a paper shape into three dimensions. I just get a crumpled wad, a little damp from neuronal exertion.

So I suppose it only makes sense that I cannot reliably maneuver my personal person in space without banging into things.

You know those movies where there’s some velociraptor with an axe stalking through a house and everything depends on the people huddling under the counters being quiet? Well. I’m the one who’s going to move that plot forward.

I prove it to myself every day. Maybe Dave is snoozing and I want to leave the room without waking him up, so I’m creeping around, going about my business and taking care to move objects with care and negotiate corners smoothly, and just as I leave the room I clip the handle of a metal pan and send it clacketing across the floor. I couldn’t do more aural damage with a drum kit.

I have run into walls misjudging where the door-hole is.

None of this makes sense. Dave, who has always been a graceful man, manages to ambulate with the ease and elegance, despite being larger than a human really needs to be (or “regular-sized,” as he puts it). I’ve seen him carry a ladder up a ladder and across a roof and set it up in perfect position first try. I would have taken out a window pane. In fact I’ve seen him take the same ladder through the house and multiple staircases including a spiral staircase, smoothly calculating the corners with an inch to spare, and the ease and fluidity of a construction crane. I can follow him with a two-foot step-stool and create a whole spackle-and-sandpaper situation.

Dave knows where his freakishly extenuated body is in space at all times. I have seen him fall down only a handful of times in 48 years. And he used to drink a lot. Perhaps he has developed this ability because the consequences to succumbing to gravity are more dire for him, but I think he was born with it. He probably shot out the chute, stuck the landing, coiled up the umbilical cord neatly, handed it to the doctor, and made polite inquiry about breakfast.

On the other hand, there is no excuse for me being puzzled as to where my various body parts are at any time. Nothing on me is very far away from anything else on me. It’s a compact arrangement that I should be able to operate with a minimum of disturbance, but I don’t. I blunder around like a fat fly on a windowsill. Bam. Bam. Bam.

I am, however, squishy, close to the ground, and not at all fragile. I’ve got all that in my favor. You do you.
