I try not to think about us growing old together, mostly because I try not to think about growing old at all. Both things — the years passing, the years together — are too enormous to contemplate. But one morning, I gave in. You were asleep, and I imagined you older and older. Your hair graying, your skin folded and creased, your breath catching. And I found myself thinking: If this continues, if this goes on, then when I die, your memories of me will be my greatest accomplishment. Your memories will be my most lasting impression.
