This is a Theater, Not a Playground
Went to see the Wolverine movie in a really big theater. About halfway up the rows of seats, it had an aisle that cut across horizontally from one side of the theater to the other. Some dumb father was there with a toddler, and he let the kid run back and forth across the aisle, squealing the whole time.
I put up with it for about 30 minutes, and then finally went down to the father and said, “Do you realize the entire movie theater can hear your child, and that it’s ruining the movie for the rest of us? Please make him be quiet.” The father stared at me in complete shock, as if the concept had never crossed his mind. He left immediately with his kid.
Several people around me thanked me as I sat down.
