Nothing fans a stammer’s flames like the fear that your listener is thinking “Jeez, what is wrong with this spasm-faced, eyeball-popping strangulated guy?” But if I persuade myself that this taxing sentence will take as long as it bloody well takes and if you, dear listener, are embarrassed then that’s your problem, I tend not to stammer. This explains how we can speak without trouble to animals and to ourselves: our fluency isn’t being assessed. This is also why it’s helpful for non-stammerers to maintain steady eye contact, and to send vibes that convey, “No hurry, we’ve got all the time in the world.” (While we’re on the subject, please don’t finish off our sentences: it makes us feel like doomed contenders in a hellish, eternal game of Countdown.)
