As the cab crossed the river, Madeleine took off her cap and gown. The interior of the car smelled of air freshener, something noninterventionist, like vanilla. Madeleine had always liked air fresheners. She’d never thought anything about it until Leonard had told her that it indicated a willingness, on her part, to avoid unpleasant realities. “It isn’t like the room doesn’t smell bad,” he’d said. “It’s just that you can’t smell it.” She’d thought she’d caught him in a logical inconsistency, and had cried out, “How can a room smell bad if it smells nice?” And Leonard had replied, “Oh, it still smells bad all right. You’re mistaking properties with substance.”

These were the kinds of conversations she had with Leonard. They were part of why she liked him so much. You could be going anywhere, doing anything, and an air freshener would lead to a little symposium.
