Other letters simply relate the small events that punctuate the passage of time: roses picked at dusk, the laziness of a rainy Sunday, a child crying himself to sleep. Capturing the moment, these small slices of life, these small gusts of happiness, move me more deeply than all the rest. A couple of lines or eight pages, a Middle Eastern stamp or a suburban postmark . . . I hoard all these letters like treasure. One day I hope to fasten them end to end in a half-mile streamer, to float in the wind like a banner raised to the glory of friendship. It will keep the vultures at bay.
