She had somehow given over the thinking to him, and in his absences her every action seemed automatically governed by what he would like, so that now she felt inadequate to match her intentions against his. Yet think she must; she knew at last the number on the dreadful door of fantasy, the threshold to the escape that was no escape; she knew that for her greatest sin now and in the future was to delude herself. It had been a long lesson but she had learned it.

~ F. Scott Fitzgerald, Tender Is the Night
