I used to feel like that almost all of the time. Nowadays it happens less often, maybe that's because I go out socially a lot less often at the moment. Also I think it's helps that I've been lucky to find a working environment which is populated by people with whom I have quite a lot in common. I've hear several people say that they simple cannot engage in small talk, since they have no idea how to begin and that they prefer to talk about deeper topics. I have this characteristic too. Maybe it's a difference in the way we think. I don't think you're alone in feeling this way
