Thanks for sharing. > I didn't know a janitor who thought that nurses or doctors didn't do valuable work (greatly more valuable than their own). More than once I've heard staff (not janitors though) talking depreciatively about doctors (e.g. "he thinks he knows everything", "he said X but my uncle says Y"). I think if you read what I wrote a bit more charitably you'll see that my point wasn't really about janitors. I used them figuratively to comment on OP's attitude that seemed like the terrible combination that is confidence and ignorance.
