Not a great position to start from, to expect everyone to be boring and only capable of inane chit-chat.  It's amazing what you find out about people when you give them a chance to talk about themselves and amazing how it broadens your own horizons. - and sometimes you find some common ground and a connection with people where you wouldn't have expected.  If you've already lumped all people into the "not worth my time" category, you'll never find out.
