How does a story change depending on the person who tells it?​

The story changes because each person has gone through something different. For example, if the protagonist told the story it's going to lead more towards how they felt, what they saw, and the journey of, "I am the hero and i have to defeat the villain!", but if the antagonist was telling the story it might lean towards their point of view, and why they became the "villain" in the first place.
