I used to feel that way. But, after some contemplation, I realized how conceited that is. People are so multidimensional and have such varying experiences that it is arrogant to think that there is nothing interesting about someone you have just met. They may not be good at communicating and they may seem to be boring or shallow. But, they almost certainly have knowledge and experiences that are foreign to you. The trick is finding what they are. If someone can't find anything interesting about another human being, it probably says more about their lack of wonder than about the target's "interestingness" (although sometimes communication is the problem too). I really like watching Dirty Jobs with Mike Rowe to see him converse with the people he is working with. If you were small talking with these people in the dentist office they might seem boring. But, Rowe is able to bring out their interestingness.
