One reason could be that they have a small repertoire of stories they consider interesting or relevant. They might not have many new experiences to draw from, so they repeat the ones they know.
Your friend might repeat stories because they really want to make sure you understand or remember the point of the story. It could be important to them, and they feel like repeating it will drive the message home. Another possibility is that they enjoy the reaction they get when they tell the story and are seeking that positive feedback again.
Maybe they find your stories really interesting and want to relive them. Kids at that age often repeat things they enjoy.
It could be that she really likes those stories and wants to emphasize certain points in them. For example, if it's a family story with important values, she might repeat it to make sure we remember those values. Also, as she gets older, her mind might work in a way that makes her think we haven't heard it before even if we have.
Maybe they just want to be the center of attention. By exaggerating stories, they can make themselves seem more interesting and get more reactions from others.
It could be that your friend has a vivid imagination and has trouble differentiating between reality and fantasy. Or they might feel the need to stand out and be noticed by telling larger-than-life tales.
Maybe your friend is just really creative and has a vivid imagination. Sometimes people make up stories to entertain themselves or others.
Sometimes, people repeat stories because they are seeking validation. By retelling the story, they hope to get the same positive response from you as they did the first time. It could also be that they are trying to emphasize a point or a feeling that was associated with the story, like how much fun they had or how scared they were. So, they keep repeating it to make sure you understand the significance of the event.
Maybe they're seeking attention. By making their stories more exciting or extreme, they hope to get more focus from others.
Audience demand also plays a part. Some stories are very popular, like those about celebrities or major global events. Online channels repeat these to attract more views. If a story about a famous actor's new movie was successful in getting clicks the first time, they might repeat it to catch the attention of new or forgetful viewers.
Old people might repeat stories because it helps them remember the past or because those memories are very important to them.
It could be that your friend didn't finish uploading it properly or there are access restrictions. Sometimes, servers can have issues too.
