Why do listeners feel compelled to call or email their "corrections" to us? Do they really think we don't know when we make a mistake? I assure you, when I slip up on the air I am the first one to know and cringe.
I got an email from a listener this morning correcting me on my pronunciation of a particular word. I knew I mispronounced it as soon as it came out of my mouth. I didn't need him to inform me. In fact, I suspect he's mispronounced words on more than one occasion in his life. But no one was broadcasting his mistakes to millions of people.
Sometimes I just want to challenge the complainers to come in and do my job for one day so that I can point out all of their mistakes. It's not easy to be on the air for four hours, reading dozens of announcements, timing all your words to a clock and making it all sound smooth and pleasant -- all without making a single mistake.
