People who think they are experts about a subject, let's say health as an example, and in reality know absolutely nothing at all. On top of it all they come across really ignorant.
These are also the people that can't hear a word you say about their health (for example).
Thanks guys. Not much taken - just have to replace credit cards, license, etc... After thinking about it all day, I guess I feel kind of sorry for the person who did it. I can't imagine how bad things must be for that person that they would be doing something like that on Christmas Eve! Pretty sad really.
