I knew what was to be found at the back of every closet, which beds had the most dust balls beneath them, which ceilings the most interesting stains, where exactly the patterns in wallpaper repeated. I knew how to cross every room in the house without touching the floor, where my father kept his spare change and how much you could safely take without his noticing (one-seventh of the quarters, one-fifth of the nickels and dimes, as many of the pennies as you could carry). I knew how to relax in an armchair in more than one hundred positions and on the floor in approximately seventy- five more. I knew what the world looked like when viewed through a Jell-O lens. I knew how things tasted—damp washcloths, pencil ferrules, coins and buttons, almost anything made of plastic that was smaller than, say, a clock radio, mucus of every variety of course—in a way that I have more or less forgotten now. I knew and could take you at once to any illustration of naked women anywhere in our house, from a Rubens painting of fleshy chubbos in Masterpieces of World Painting to a cartoon by Peter Arno in the latest issue of The New Yorker to my father’s small private library of girlie magazines in a secret place known only to him, me, and 111 of my closest friends in his bedroom.

What on earth would I do if four bears came into my camp? Why, I would die of course. Literally shit myself lifeless.

Every human body consists of about 10 quadrillion cells, but about 100 quadrillion bacterial cells. They are, in short, a big part of us. From the bacteria’s point of view, of course, we are a rather small part of them.
