One of my coworkers happened to be in the studio with me for a few moments this afternoon while I was on the air. After I turned off the mic, he started chuckling and said "I never realized how much you wiggle around while you're on the radio."
I was surprised. No one ever pointed that out to me before. But I realized why I do that. It's because I'm so short that I have to raise the chair up high so I can reach all the buttons on the radio console. And that leaves my feet swinging.
