"A silence would be awkward"

One reason the reply has to be ready is so that it can be delivered the instant the other person stops. It rarely gets examined, but the fear underneath is of the gap. If they finish and you have nothing prepared, there'll be a silence. The silence will be awkward, and you'll be to blame for it.

The fear has a basis. Stivers and her colleagues found that speakers of all ten languages they studied keep the silences between turns as short as they can. We're tuned to fast handovers, and a pause that runs long is noticeable. It's true as well that in some situations, such as a job interview or a first date, a long silence can feel uncomfortable.

But consider the scale. The normal gap is about a fifth of a second. A pause of one or two seconds, which is all I'm going to suggest, is long by the standards of a stopwatch. In a conversation it's short. To you, the one who's pausing, it feels enormous, because you're inside it and aware of having nothing ready. I think the other person reads it differently, though this is my reasoning and not a finding. They can see that you're thinking about what they said. After someone has told you something that matters to them, a short pause is a compliment. It tells them you've taken in what they said and aren't going to answer it glibly.

Compare the reply that comes with no pause at all. If you start speaking in the same instant they stop, or a little before, you were obviously ready. To be ready, you must have stopped listening at some earlier point. A reply that arrives that quickly was composed while they were still talking, and at some level they know it.

The gap is also useful to them. People often haven't finished when they stop. They've paused to see how it's going down, or to find the next word, or to decide whether to say the harder thing. A listener who leaps into every pause never hears what would have come next. If you wait a second or two, a good proportion of the time they carry on, and what they add is often the real matter. Counsellors and interviewers know this well. One of the most productive things you can do in a conversation is to stay quiet for a moment longer than is comfortable.

It helps to know that you can get through the gap without having anything clever to say. Chapter 12 deals with the fear of having nothing to say at all. For now, notice that the beat doesn't have to be empty. You can fill it with a small acknowledgement that commits you to nothing, such as "Mm", or "Right", or "Gosh". Make the sound slowly, and let it cover the second or two in which you take in what they said.

Some people worry that pausing will make them seem slow, or lose them their turn in a fast conversation. In a lively group that's a real consideration, and chapter 15 looks at it. With one other person, though, and particularly someone who's telling you something that matters to them, nothing is lost. The other person isn't timing you.
