You can use the classic five-paragraph structure for your autobiographical essay if your ideas fit it.

In this manner, readers will easily follow your thoughts.
What else happened after each of these main events? What was important to you at this time? Did you have any special friends? A pet? A romantic partner? A spouse?

What single act of kindness most stands out when you think of this person? Write about that. What actions and dialogue can you relate in concrete detail to help readers understand that relationship and its importance?
