Great example of what you’re prone to, Mina. Listen to the Elizabeth Warren episode you so capably steered. Serious issues, and an appropriately sober tone during the first 2/3 of the broadcast. And THEN. When you laugh during the question you’re asking, it communicates a lot, and all that laugh-borne signaling is bad for the content, quality, and direction of the discussion. You’re laughing at yourself, with yourself, and it tends to demean the topic.
It is humble, granted. And human. But it quickly becomes excessive. You’re way too committed to your craft and prepared for your work to let things slip like this.
My hunch is that no one around you brings up this weakness and the opportunities it presents for improving upon your excellence and your command. Because if you get the message on this, you’re sure to be more intent on overcoming it than any mere listener like myself might readily understand. Relax, sure. Be personable with guests and callers, definitely. But in the end, neither of those worthy ends is served by giggling.
