A few hundred feet from the Pyramid, I bent down, scooped up a handful of sand and then, a little farther away, let it silently spill. Under my breath I said: I am modifying the Sahara. The deed was minimal, but the words, which were scarcely ingenious, were exact, and I considered that I had needed an entire life to say them. The memory of that moment is one of the most significant of my stay in Egypt.
