“I got incredibly heavy boots about how relatively insignificant life is, and how, compared to the universe and compared to time, it didn't even matter if I existed at all.”

“I read the first chapter of A Brief History of Time when Dad was still alive, and I got incredibly heavy boots about how relatively insignificant life is, and how compared to the universe and compared to time, it didn't even matter if I existed at all. When Dad was tucking me in that night and we were talking about the book, I asked if he could think of a solution to that problem. "Which problem?" "The problem of how relatively insignificant we are." He said, "Well, what would happen if a plane dropped you in the middle of the Sahara Desert and you picked up a single grain of sand with tweezers and moved it one millimeter?" I said, "I'd probably die of dehydration." He said, "I just mean right then, when you moved that single grain of sand. What would that mean?" I said, "I dunno, what?" He said, "Think about it." I thought about it. "I guess I would have moved one grain of sand." "Which would mean?" "Which would mean I moved a grain of sand?" "Which would mean you changed the Sahara." "So?" "So? So the Sahara is a vast desert. And it has existed for millions of years. And you changed it!" "That's true!" I said, sitting up. "I changed the Sahara!" "Which means?" he said. "What? Tell me." "Well I'm not talking about painting the Mona Lisa or curing cancer. I'm just talking about moving that one grain of sand one millimeter." "Yeah? If you hadn't done it, human history would have been one way..." "Uh-huh?" "But you did do it, so...?" I stood on the bed, pointing one of my fingers at the fake stars, and screamed: "I changed the course of human history!" "That's right." "I changed the universe!" "You did." "I'm God!" "You're an atheist." "I don't exist!" I fell back onto the bed, into his arms, and we cracked up together.”

“I thought for a minute, and then I got heavy, heavy boots.”

“I didn't understand why I needed help, because it seemed to me that you should wear heavy boots when your dad dies, and if you aren't wearing heavy boots, then you need help.”

“I felt, that night, on that stage, under that skull, incredibly close to everything in the universe, but also extremely alone. I wondered, for the first time in my life, if life was worth all the work it took to live. What exactly made it worth it? What's so horrible about being dead forever, and not feeling anything, and not even dreaming? What's so great about feeling and dreaming?”

“My boots were so heavy that I was glad there was a column beneath us. How could such a lonely person have been living so close to me my whole life? If I had known, I would have gone up to keep him company.”

“Well, what I don't get is why do we exist? I don't mean how, but why.' I watched the fireflies of his thoughts orbit his head. He said, 'we exist because we exist. . .we could imagine all sorts of universes like this one, but this is the one that happened.”
