A memoir is a personal account of events from the author's life, and as such, it is subjective and may contain errors. Memoirs often include the author's thoughts and feelings about events, which can be difficult to convey accurately. Additionally, people's memories can be fallible, and events may be remembered differently over time.
While accuracy is important in a memoir, it is not the only factor to consider. A memoir is also a work of art, and the author may use literary devices such as symbolism, metaphor, and foreshadowing to create a more powerful and engaging narrative. As a result, some events in a memoir may be exaggerated or embellished for dramatic effect.
Ultimately, the decision of how much accuracy to include in a memoir is up to the author. There is no right or wrong answer, and what is important is that the author is honest with their readers about the events they are describing.
