Use the "Triple Nod" for More Engaging Small Talk
It's not easy for everyone to turn small talk into conversation
The triple nod is the non-verbal equivalent of the ellipses. It is a nonverbal cue for someone to keep talking. If you are introverted and aren't great at making conversations, you want to encourage the person you are speaking with to keep talking. Once they are done speaking and pause, nod three times in quick succession and they will often continue. If not, you can pick up where the conversation left off, but this is a great way of showing engagement and lengthening a discussion.
The video above shows the triple nod in action, and also includes one more tip from Van Edwards: the elbow touch. Watch the video or read the article for more body language tips.
