I still remember a conversation from high school during which the yearbook advisor (I was on the newspaper staff) embarrassed me for saying I was trying to do a professional job of something.

He told me I was using the word improperly. Now that I'm a teacher myself, I don't think it was right for a grown man to try to shame a teenage girl, especially when we're talking about the same distinction.

Yeah, I think that guy was kind of a jerk.
