Robert Fulghum's new book begins with a question we've all asked ourselves: What on Earth have I done? As Fulghum finds out, the answer is never easy and, almost always, surprising. For the last couple of years, Fulghum has been traveling the world — from Seattle to the Moab Desert to Crete — looking for a few fellow travelers interested in thinking along with him as he delights in the unexpected: trick-or-treating with your grandchildren dressed like a large rabbit, pots of daffodils blooming in mid-November, a view of the earth from outer space, the mysterious night sounds of the desert, every man's trip to a department store to buy socks, the raucous all-night long feast that is Easter in Greece, the trials and tribulations of plumbing problems and the friendship one can strike up with someone who doesn't share the same language.
