What is a good topic for an autobiographical narrative?

Question

I know autobiography means about you but what are good topics that reveals something important about yourself but there should be conflict at the center of this?

I was going to write about a friend who passed away and we had fought before he died, but my teacher said it shouldnt be sentimental? Does that idea seem sentimental?

Answer 3

It might be -- depending upon his requests and your reasons for following them.
