TDPRI John would have pretended to go out and water his front garden of nice Gerbras.. and turn the hose on the guy.... to see if he put his wipers on..

Why not ask him if he's ok? I did that once and when I approached the car it became obvious that he was a plain clothes police officer who was waiting for something to happen on a nearby block. Still, its your neighborhood and bad guys don't like people to notice them.
I would have approached the car and rapped on the window.......I called the police, would you have called the police?
I got home from the office at 4 o’clock. There was a car in front of my house, an SUV. The engine was running the lights were on, and there was a short old man sitting still in the car with his head against the head rest. He wasn’t doing anything wrong he was just sitting there in front of my house. This is really unimportant but I bought a new microwave today at Best Buy because my microwave died. It took me about 45 minutes to move the new microwave in the house and haul the old microwave out to the dumpster and go back-and-forth. After 45 minutes the guy was still sitting still in the car with the engine running and the lights on. Then I brought some groceries in and the guy was still sitting in the car. Then I took some trash out from the kitchen and the guy was still sitting in the car. The dude was sitting there for an hour with the engine running and his lights on and he was absolutely still.
He was not a neighborhood guy. The elementary school school bus pulls up to my corner and I have 25 kids standing on my corner every morning. Many of their parents will drive them to the corner and I know their cars because they park around my corner to take the kids to the bus.
At the one hour mark I thought, I hope this guy isn’t sick, I hope he didn’t have a stroke, I don’t know what’s going on.
I called the police and I said this gentleman isn’t breaking the law but I’m a little worried he’s been sitting with his engine running and his lights on and he’s absolutely still and he’s been in front of my house for an hour. I actually called the cops and I’m not an uptight person by any means and I’m a live and let live guy but I’m looking at this guy and he’s just sitting there.
I call my mom every evening when I get home from work because she’s almost 90 and I care about her and I called her. I called my mom and describe the scenario. Three minutes later I get a call from a woman police officer in a cruiser and she said I’m at your corner and there’s no car there and I looked out the window in the car was gone in a couple minutes when I called my mother the guy Musta drove away.
Hit me hard, was a goofy for calling the cops? I didn’t feel comfortable approaching the car and wrapping on the guys window, I really didn’t know what to do, I just thought it was kind of freaky. Did I overreact? What would you have done if it was your house?
