When you take the time to listen to someone, really take the time to listen properly; it shows you value the person, which is the ultimate form of respect. If you look bored or interrupt the person, you're showing that you don't really care what they have to say.
According to Dr. Beth Cabrera, treating others with respect is essential for establishing positive relationships. Leaders show respect by giving others their undivided attention. They ask people for their ideas and really listen to what they have to say, and as a result, it makes people feel respected as worthwhile, competent individuals.
Remember, you are the leader; you have to lead by example and set the tone for everyone to follow. So when you are having a conservation with someone, make that person, at that moment, the most important person in the world because it shows a level of respect and appreciation for what they are actually saying and, in the process, permits others to do the same.
