“ My mother says it can't stay like this, but I believe it will. The Pants are like an omen. They stand for the promise we made to one another, that no matter what happens, we stick together. But they stand for a challenge too. It's not enough to stay in Bethesda, Maryland, and hunker down in air-conditioned houses. We promise one another that someday we'd get out in the world and figure some stuff out. ”
