It's still fascinating to show up to a professional meeting and see people not talking to each other people wait for the meeting to begin. It's easier and less awkward now that people have personal technology they can hide in. When I typically start talking to anyone I realize more that many people consider themselves to be introverts who don't necessarily have facility in starting conversations with anyone. They often join when invited. It is vital that we help people free to interact together with their best in any context.
