Well, you know. Not "new," but "heretofore unreleased," or... I don't know. Something.

Look: The New Yorker has a David Foster Wallace story you haven't read before.

Once when I was a little boy I received as a gift a toy cement mixer. It was made of wood except for its wheels—axles—which, as I remember, were thin metal rods. I’m ninety per cent sure it was a Christmas gift. I liked it the same way a boy that age likes toy dump trucks, ambulances, tractor-trailers, and whatnot. There are little boys who like trains and little boys who like vehicles—I liked the latter.

It was (“it” meaning the cement mixer) the same overlarge miniature as many other toy vehicles—about the size of a breadbox. It weighed three or four pounds. It was a simple toy—no batteries. It had a colored rope, with a yellow handle, and you held the handle and walked pulling the cement mixer behind you—rather like a wagon, although it was nowhere near the size of a wagon. For Christmas, I’m positive it was. It was when I was the age where you can, as they say, “hear voices” without worrying that something is wrong with you. I “heard voices” all the time as a small child. I was either five or six, I believe. (I’m not very good with numbers.)

I liked the cement mixer and played with it as much as or more than I played with the other toy vehicles I owned. At some point, several weeks or months after Christmas, however, my biological parents led me to believe that it was a magic and/or highly unusual cement mixer. Probably my mother told me this in a moment of adult boredom or whimsy, and then my father came home from work and joined in, also in a whimsical way. The magic—which my mother likely reported to me from her vantage on our living room’s sofa, while watching me pull the cement mixer around the room by its rope, idly asking me if I was aware that it had magical properties, no doubt making sport of me in the bored half-cruel way that adults sometimes do with small children, playfully telling them things that they pass off to themselves as “tall tales” or “childlike inventions,” unaware of the impact those tales may have (since magic is a serious reality for small children), though, conversely, if my parents believed that the cement mixer’s magic was real, I do not understand why they waited weeks or months before telling me of it. They were a delightful but often impenetrable puzzle to me; I no more knew their minds and motives than a pencil knows what it is being used for. Now I have lost the thread. The “magic” was that, unbeknown to me, as I happily pulled the cement mixer behind me, the mixer’s main cylinder or drum—the thing that, in a real cement mixer, mixes the cement; I do not know the actual word for it—rotated, went around and around on its horizontal axis, just as the drum on a real cement mixer does. It did this, my mother said, only when the mixer was being pulled by me and only, she stressed, when I wasn’t looking. She insisted on this part, and my father later backed her up: the magic was not just that the drum of a solid wood object without batteries rotated but that it did so only when unobserved, stopping whenever observed. If, while pulling, I turned to look, my parents sombrely maintained, the drum magically ceased its rotation. How was this? I never, even for a moment, doubted what they’d told me. This is why it is that adults and even parents can, unwittingly, be cruel: they cannot imagine doubt’s complete absence. They have forgotten.

The rest is here.
