One afternoon I ran into him at the bookshop where we first argued about a character’s motive. He looked the same and different — better rested, maybe. He smiled that polite smile and we did the brief, awkward dance strangers do when they know too much about each other’s history. He asked how I was; I said fine. He told me about a film he’d made, a modest success. I surprised myself by saying “congratulations” without tasting vinegar. The exchange was small, functional, ordinary. It felt good in a way I hadn’t expected.
