Life's best moments
Deitsch sent a Tweet of his own, asking his followers, "How many of you have a photograph of the single best moment of your life?"
Within minutes, answers, in the form of photos, came rushing in: Parents' first moment with a newborn, the moment he asks and she says yes, the moment of homecoming from the danger of war. Dozens, then hundreds of photos streamed in, in what Deitsch describes as a "fountain of humanity."
