In spite of the old saying, people still shoot the messenger. Some how, I ended up being the one at my company that has to inform our contributing artists that we need changes made to their work. No matter how nice I am about it (and folks, I'm nice to a fault), there's always the people who take offense, and end up hating my guts for delivering constructive criticism. I can hardly blame them, because I don't handle criticism of my work very well either, but it takes its toll, week after week after week.

EDIT: I should add that I'm being dramatic. They probably don't hate my guts, but the impatience and frustration they feel is palpable.
