According to the story, a good listener should show empathy. That means trying to understand the feelings of the speaker. If someone is sad while talking, you can give a sympathetic look or a gentle touch on the arm to show you care. Also, don't interrupt. Let the person finish their thoughts before you start to talk. This gives them the respect they deserve and also helps you to fully understand what they are trying to say.
