I'm sorry you had that experience at the movies.
two elderly women sat about three rows in front of us and did a running commentary at the tops of their lungs for the ENTIRE FILM
I had this experience with the ladies sitting behind at the ballet this weekend. HELLO! Ladies, they can hear you. We all can hear you. And if you really didn't know the story of Sleeping Beauty before you walked in, maybe you should've read the fairy tale before you showed up.
That being said, the ballet itself was lovely, and my brother and sister both were quite well behaved. I was proud of them.
