Experience thunderstorms under a tin roof and a walnut tree, and the romantic thrill of discovering Whitney, NE, and not going there. Remember digging holes, trying to learn to dance, and flying kites with kids. Spend a day with shrubbery, spies and guacamole. Gain insights into strategic deafness. Become Bda.

But don't be surprised if these essays pop into your head just when you need them, like memories of pleasant times with an old friend.
