Mr. Morrison's statement at the end of his story "I makes myself remember." why do you think he makes himself remember.

He makes himself remember how his parents were killed when he was six years old. The "night men...swept down like locusts" on his house and set it on fire. His sisters were also killed in the fire. His mother saved him from the burning house before being killed. People say he was too young to remember but he forces himself to remember. He will never let that happen again.
