I don't get it either, and have faced people like this, some in my own family. I like to think that we are all on the same plane and equal. I don't know what it is about people having issues and people feeling like they are better because they either a. don't have those same issues or b. are too scared to talk about their own issues, which they do have. But I'm sure there's some kind of psychology around it. Talk to people you feel safe around and forget the rest.
