What is a limitation of the first person narrator

The answer is the narrator might not be aware of the thoughts or actions of other characters

Explanation:

First person narrator is a narrative style. It is characterized by the use of first person by the narrator along all the story. Even though it can be useful for some types of narratives (such as autobiographies or short stories,) this perspective narrates what the speaker/character considers important and cannot know what the others characters think about a situation.
