Jack forgot he was an alcoholic, conveniently, and went on a bender. In the morning, as he worshiped the God of Porcelain, his desire for the woman he'd picked up during the night --what was her name, Claudia--and was it a woman -- had vanished, and oddly, her desire for him vanished as well--she had seemed so devoted. He could barely remember her name, or his own, let alone where the keys to his car were. Had he driven his car? He tried to remember what 20 years of sobriety had been like, and failed. Tomorrow he would have to count one day. Before he drank again, he'd call his sponsor.
