I began to defer, always, to the judgment of others. If Drew remembered something differently than I did, I would immediately concede the point. I began to rely on Drew to tell me the facts of our lives. I took pleasure in doubting myself about whether we’d seen a particular friend last week or the week before, or whether our favorite crêperie was next to the library or the museum. Questioning these trivial facts, and my ability to grasp them, allowed me to doubt whether anything I remembered had happened at all.
