A special group of people

Think of a group of people. Now think of a group of people whose members it seems you will never come across or meet. For instance, I don't think I'll ever talk to a member of the Thai royal family, or the politburo of the Chinese Communist Party. I met someone who is in a group of people that I never thought I would meet tonight. I'm going to give you some clues and unfortunately, everyone will probably be able to figure it out.
