I was walking out of the grocery store the other day, arms full of bags. Older
lady in the handicapped spot was starting her SUV up, oblivious to the fact that the cart jockey had placed a line of 20ish carts behind her truck. I drop my bags (yes, actually dropped them) ran over, started pushing the line of carts out of her way, since she was oblivious of them. She starts backing up, I'm pushing carts and POUNDING on her back window, yelling for her to stop. She does not. She backs up, pushes the carts about a foot, puts it in forwards, and drives away across the yellow lines.
So, she hit the carts, would have hit me, was oblivious to it all, AND I now had a line of 20 carts slowly picking up speed down the slight slope of the parking lot, all while my bags sat there on the asphalt.
It was wonderful. I hate oblivious people.
