In a conversation, listening assumes paramount importance. A good listener keeps the conversation going smoothly and productively. Listening is an important skill one needs to acquire. It requires a good amount patience too!
If we think that we know what other person is going to talk about, it impairs our listening ability. Listen carefully while others talk. That is one way to show respect. May be the other person is trying to convey something important. All we have to do is to suppress the urge to talk, but listen! The bible puts it this way
Know this, my beloved brothers: Everyone must be quick to listen, slow to speak, James 1:19
