Susan waged a vendetta against me for some time, disrupting my phone service, and giving the phone company orders to disconnect my telephone number. My one small act of revenge came about by chance. Once, in the middle of a phone company hack, I needed one telephone line that would ring and ring, unanswered. I dialed the number of a pay phone I happened to know by heart. In one of those small-world coincidences that happen to most of us now and then, Susan Thunder, who lived nearby, was walking past that particular phone booth just at that moment. She picked up the telephone and said hello. I recognized her voice.
