" Up the street a song cloud floats by, sagging a bit, but still intact. I walk faster and catch up with it just in time to hear the ending, a symphony orchestra, the sound full and resplendent, and it is one of those times, you know those times every so often when you hear the right piece of music at the right time, and it just makes you think. "
