Sometimes, when there are fewer new experiences in life, people tend to go back to the old ones. Your mom might not have a lot of new things to talk about, so she keeps repeating the same stories which are familiar and comforting to her.
You could gently remind her that she has told you the story before. Maybe say something like 'Mom, I love that story, but you've told it a few times already.'
One possible reason is that she has a limited set of memories that are very important to her, so she keeps repeating them. Maybe those stories are the ones she cherishes the most from her past experiences.
If you don't want to be so direct, you can try to steer the conversation in a different direction when they start repeating the story. You can bring up a new topic related to something else you both like, like a new movie or a book. This way, you can avoid hearing the same story again without making your friend feel bad.
You could gently let your friend know that you've already heard the story. For example, say something like 'Oh, you told me this really interesting story before. I still remember it clearly.'
You could say something like, 'Mom, I love that story so much, you've told it before and it always makes me smile. But we can talk about something new now.' This way, you show that you appreciate the story while also gently indicating you've heard it.
Well, when Biden repeats the same story, it might be part of his political strategy. By repeating certain stories, he can shape public perception. For example, if he has a story about a successful policy implementation, repeating it can reinforce the idea that his policies are effective in the minds of the public. Also, it could just be a normal human tendency to go back to familiar narratives, especially when he wants to connect with his audience on an emotional level.
The repetition in the Batman graphic novel could be for various reasons. It could be to showcase the complexity of the story when seen from multiple angles or to create a sense of familiarity and comfort for fans.
Maybe she just has a limited repertoire of stories. Or perhaps those are her favorite stories and she wants to share them over and over again because they hold special meaning for her.
It could be that she has dementia or early signs of memory loss. As people age, their memory can decline, and they might not realize they are repeating stories. Another reason could be that those stories are very important to her, and she wants to make sure you remember them. Or it might just be a habit she's developed over time without realizing it.
