Maybe they are trying to create a narrative that compares and contrasts the two stories. This can be useful in various fields such as literature or journalism. In a feature article, a writer might tell their own experience of traveling to a place and then also tell the story of a local they met there, to show different perspectives on the same location.
It could be to show empathy. By telling his story as well as their own, they are demonstrating that they understand and respect the other person's experiences. For example, in a therapy session, a person might talk about their own journey and also about how their partner has been affected by the same situation. This helps the therapist get a more complete view of the relationship dynamics.
One reason could be for the sake of honesty. They want to present a full picture that includes both their own side and another's.
It could be that their story involves something that they think others won't understand or believe. For example, if it's a very strange or personal spiritual experience.

It could be that the story involves something that the dad has strong opinions against.

So, to avoid that negative outcome, they say 'never tell dad story'.
It can help you relieve stress. When you share your story, especially if it's something that has been bothering you, it's like lifting a weight off your shoulders.
Maybe someone who has had a long and eventful journey. They put on their robe, which could be a reminder of their travels, and then start to tell their story. It could be a way for them to create a certain atmosphere, both for themselves and for the listeners.
Maybe because they know some facts about the real - life story that the movie is based on that the movie didn't show. For example, if they knew of specific players who had unique experiences not in the movie.
