There is possibly a third reason. It happened to me. Mrs. Guthrie may have provided aid or comfort to someone in need and that individual became obsessed with her. I worked in a congressional office in the district. A man came to the office seeking help with his federal retirement. At first blush he appeared reasonable and calm. That changed quickly. I offered him some candy and a glass of water while waiting on the phone with the federal office. Thereafter, he started coming to the office day after day, leaving up to 15 messages on the answering machine at night, peering in the window at me at night, etc. I’m ashamed to admit I didn’t give it much thought until he followed my coworker home and asked if I lived there. The police picked him up, a hearing was held and he was committed to the state mental facility because he posed a very real threat. Ultimately it all came down to “but, she gave me the sweets.”Money or Attention/Fame are really the only 2. And revenge.
