I can tell you that many people have exciting and memorable experiences when they meet celebrities accidentally. Meeting a celebrity unexpectedly can be both thrilling and surprising. Some people might feel star-struck, while others may approach the encounter with a sense of calm and respect for the person's privacy. The experience largely depends on the individual's personality and their feelings towards the celebrity in question.
Keep in mind that celebrities are regular people too, and they appreciate respectful interactions. Always be considerate of their personal space and remember that they deserve privacy just like anyone else. It's essential to treat them with kindness and respect if you happen to encounter them in public.
