Found on an elementary school in the Potrero Hill neighborhood. Pretty inspiring graffiti, not just for the tots, but for us all….
The quote is from the Neil Gaiman comic The Sandman. The complete quote is:
Birds of a thousand colours danced in the sky when I was a boy. They brightened the day with their intricate songs. “We are who we choose to be,” sang the goldfinch, when the sun was high. “I dream about dreams about dreams,” sang the nightingale, under the pale moon.
Master Li, in SANDMAN #74, “The Exile”
