Erica

“Her gray, sun-strained eyes stared straight ahead, but she had deliberately shifted our relations, and for a moment I thought I loved her. But I am slow-thinking and full of interior rules that act as brakes on my desires, and I knew that I had to get myself definitely out of that tangle back home. I'd been writing letters once a week and signing them: "Love, Nick," and all I could think of was how, when a certain girl played tennis, a faint mustache of perspiration appeared on her upper lip. Nevertheless there was a vague understanding that had to be tactfully broken off before I was free. Everyone suspects himself of at least one of the cardinal virtues, and this is mine: I am one of the few honest people I have ever known.”
