As with any social group, new members pop in and try to join the conversations. Sometimes they don't understand the social rules of the culture and make inappropriate comments, dominate conversations, or otherwise embarrass themselves. In time, these folks either conform to the norm, move on, or cause others to move on. Unfortunately, they rarely see that they are the problem and, instead, point the finger at others. Years ago my wife, who is a psychologist, taught me an important lesson. She said, "We each live in our own reality." That helps me understand how people can be completely out of line yet think they're fitting in nicely. While I might be annoyed, I understand. Dennis
