Before my dog died, ""natural causes"", I took him nearly everywhere. I would roll the windows up, turn the air on high, and lock the doors. Then start the engine with the remote control.
One day, I noticed a guy giving me the evil eye as I locked the doors. I turned and hollered at the car, ""Star, if it gets hot, start the engine and turn the air on."" Then, in my pocket, I hit the remote start. You have never seen such a shocked look on a man's face.
