We lead with listening
Because we look at communication with an eye to improving understanding and improving relationships, we listen for what people really care about. We can take on the perspective of the other person in an interaction and we know how to peel back to get at underlying assumptions. Additionally, because we are trained for listening to the nuances of the ways that people talk, we can use our listening to help us talk in ways that mirror and resemble those of the people we are talking to, which enables us to better hear and be heard. This skill builds rapport.
Basically, we pick up on things. We are sharp observers and this skill is marketable in any context!
