I avoid flying, but last time I flew I ended up in the middle seat, flanked by two very large ladies who were "together," and proceeded to talk loudly back & forth as if I didn't exist. I spoke up and said, "I hope you don't mind if I join your conversation," and proceeded to do just that. They seemed a little shocked at first, but they weren't about to change seats, and meanwhile, I refused to shut up and be their quiet little human arm rest. So, we all had a chat until the window seat lady decided to take a nap, and I finally got to read my book.
