Recently, I've been a font of wisdom for the young people: I coined a new aphorism about poison ivy for my oldest son-- leaves of three, do not pee-- and I gave some invaluable advice to a student of mine, who stashed his very expensive philosophy textbook on a cart in the corner of the classroom, so he wouldn't have to carry it around in his knapsack . . . I told him: never hide something valuable on a thing with wheels, hide it in something stationary . . . because the cart is gone, someone wheeled it away-- as people are wont to do with carts-- and I've asked around, but no one seems to know who wheeled the cart away or where it is-- so this lesson is going to cost him some cash; my most committed readers will recognize that this lesson about not putting valuable things atop things with wheels is the seminal lesson from this blog, the thing from which all other sentences sprung (and those committed readers might also remember that I was far less prolix in those days).
