True stories:
8 page handwritten letter at work from woman wanting us to check out her stolen identity (this was before actual identity theft got big). Seems she was actually an heir to the Getty oil fortune, but had been robbed of her identity through "reverse mirror handwriting" and having new fingerprints surgically transplanted onto her fingertips. Not only that, but she was being victimized by a conspiracy of detectives and investigators that had for some strange reason ignored all her reports, probably in exchange for a piece of the money. Return address was traced to a 'home'.
Man wrote to advise how he'd been taken for what must have been involuntary surgery -installing implants in his mind that were being used by mysterious people and government agencies to do such things as transmit signals that caused him to wet his pants on airplanes, put voices in his head, suppress memories of abduction, etc.
After 3 hours on the road to give a talk, I got out to stretch, adjust crotch, etc. Woman I'd never seen before in this (or any other) life came up to me at the rest stop and let me know that she was onto me, knew I'd been following her for 3 days, hoping to nail her for insurance fraud of some kind. I should have offered her a chance to get it all off her chest and set things straight, but I had to make my appointment.
I must have been pretty obvious, in my generic white rental car, with sunglasses & briefcase. Made!!
