On a note related to Hoss429's post about the woman that thought he was following her.
I play the state lottery (I know it's a sucker play) and have my tickets checked by having them scanned at the local station. On one particular day the message came back that I should sign the ticket immediately and cash it in at a state lottery office. That meant that the winnings were more than the $500 that the station can pay out, but it doesn't show how much the winnings are. I took the ticket and walked back out to my truck. As I pulled out, I noticed that a guy that had been standing in the store when the attendant told me about the message pulled out behind me.
I made a couple of turns on my way home and he made the same turns. I got suspicious and made a right turn onto a side street. He made the same turn. I made another right turn at another side street and he followed. These were completely random turns. I made a couple of lefts and he followed those too. This was in a large neighborhood. After another random turn, he must have figured out that I knew he was following me and broke off his chase. I took a completely unusual route back to my house. I didn't want this guy to know where I lived.
I know this sounds paranoid, but I'm sure he was following me. The winnings turned out to be $1500. People have been killed for a lot less than that and this guy knew I had a ticket that was worth something. May have even been the jackpot as far as he knew.
