Two malcontents engage in a phone romance.
"We talked for a long time, more than an hour, until I got sleepy, so I started to fall asleep with her on the phone. The next night, around the same time, she called me again. I was really happy she did that. We had a nice conversation. She told me this story, how she used to prank call a math teacher of hers in junior high. She did it so much, she figured out how to reprogram his outgoing message, using his two-digit remote-access code. She redid his outgoing greetings, said things that were explicitly sexual. Her teacher didn’t understand technology or remote-access codes. He assumed someone was breaking into his house each day to rerecord his message. It filled him with fear and paranoia. He bought a dog. He had an alarm installed and got a prescription for sleeping pills. It was a long time—nearly a year—before the police identified Koko and got to the bottom of the mystery. "
