2 stories about my mom.
She was in a blockbuster in the 1990's when she noticed a guy staring at her. He had a creepy look, and seemed to not be looking at movies at all. The head cashier noticed as well. My mom went to check out, when the cashier had a worried look on his face. He asked her if she knew the guy, and she said no. As they're finishing the checkout process the cashier yells at my mom, "run to your car, now!" The guy had apparently started bolting at her from across the store with a bad look on his face. The cashier and his coworker blocked the door and tackled the guy. Police show up by the time my dad comes back to see what was going on (20 minutes later). Turns out the guy had just gotten out of a psych ward, and he'd admitted to wanting to kill somebody that night. Thanks cashier hero (cashero)!
About a decade later, she's driving my sister to school in rural Michigan at sunrise. She notices somebody in the road a few hundred feet ahead. There's a guy blocking her lane (on a 55 mph backroad), shoeless and wearing overalls (it's winter). She stopped the car about 20 feet from him thinking he needed help or something. Then she saw the axe in his hands. He apparently had an insane/evil look on his face as he sprinted at the car and raised the axe above his head. My mom threw the car in reverse and put the pedal to the floor. They got far enough away that his throw left the axe well short of their car.
tr;dr My mom has an uncanny way of running into crazy strangers who want to kill her.
