Reminds me of a Virginia story - a girl I knew in Charlottesville was convinced someone was stalking her - this was the early 80s. She had recently moved from Richmond where she'd seen two men wearing white shirts, black ties, riding a bicycle frequently in her neighborhood. Apparently there were two of similar build in her Charlottesville neighborhood as well. We had to reassure her that was the way all Mormon missionaries looked...
Hint: Knock off the attacks
