"I think a relationship is like two stories," I say at last, feeling my way cautiously through my thoughts. "Like...two open books, pressing together, and all the words mingle into one big, epic story. But if they stop mingling..." I lift my glass for emphasis. "Then they turn into two stories again. And that's when it's over." I clap my hands together, spilling champagne. "The books shut. The End." --
