Make people feel comfortable by acting like them

Watch your conversation partner. Look at the way they move, then imitate the style of movement.
For example, if your partner grabs the coffee mug with both hands, do the same.

Listen to the speaker’s arbitrary choice of nouns, verbs, prepositions, adjectives and echo them back.
For example, if a lady is using the word toddler for her kid, use the same for yours.

Use analogies from your listener’s world.
For example, if your customer has a garden, talk about “sowing the seeds for success.” or if she plays tennis, tell her it hits the “sweet spot.” This will give your points more power and punch and the other party would relate easily.

Vocalize complete sentences to show your understanding and garnish your dialogue with phrases like “I see what you mean.” or “That’s a lovely thing to say.”
Your empathy impresses your listeners and encourages them to continue.
