Most people freeze when strangers speak English at them in a foreign country. Silence is ambiguous — it leaves room for them to try again. This episode breaks down the actual tradecraft: the delayed reaction, the three-channel deception model (verbal, paralinguistic, nonverbal), and how to use props and cover languages to actively feed someone the conclusion you want them to reach. You'll learn why the 200-millisecond reaction gap betrays understanding, how a newspaper or phone screen can seed an impression before you speak, and what to do when your cover works too well and someone tries to help you.
