" We looked at each other and just laughed; everything was hysterically funny, even the playground slide was smiling at us, and at some point, deep in the night, when we were swinging on the jungle gym and showers of sparks were flying out of our mouths, I had the epiphany that laughter was light, and light was laughter, and that this was the secret of the universe. "

― Donna Tartt , The Goldfinch
