I completely sympathize with you and it annoys most sane people. My mother loved attending musical theater before her health starting making it an issue. One of the last shows we got to see was the touring production of The King and I at the Kennedy Center. We had very good seats, but a group of people with a young girl (8-10) ended up in front of us, with the girl planted directly in front of my mother. After the show started the girl proceeded to talk like she was in her living room, stand up, stand up in the chair, try to walk up and down the row she was in, etc. The older people she was with kept trying to control her without success. They finally got her to sit down, then she began stretching her very long hair out over her head and flinging it to either side of her and into the row behind. There were lots of shushes and please stops from people, including my mother. At intermission, I hoped they would remove her, but they remained for Act 2, so I switched seats with my mother to hopefully give her a break. Same thing through all of Act 2 with the hair stretched up above her head and flinging it here, there and everywhere, despite balking patrons. At the end, the older people with her apologized and said "she doesn't belong to us." OK, but so what?! They brought her to the theater and had literally no control over this child and expected everyone else to suffer the consequences. They should have just left at some point and taken her out of the theater. Unfortunately, my mother recently passed away and it annoys me beyond words that this was one of her last theater experiences.
