KATHA UPANISHAD

I was kind of confused on what the story meant. I couldn’t tell if it was because I wasn’t focused or what. I just understood that it was about people taking to each other but what they said was kind of confusing. Some parts of it made some sense but the rest just confused me. From what I read and tried to think about, the meaning probably was based off death of a person? I’m not sure if that makes sense or not.
