MIRROR people’s behaviour – one to one. They cross their right leg, you cross your left. They lean on their left hand you lean on your right. Keep doing this in a discreet way, in the course of a conversation. Then, after a while, make the first move, perhaps by rubbing your chin – if they do the same (ie rub their chin, not yours!) you have established rapport. It is amazing.
