Helpp pleas... Read the excerpt below from The Absolutely True Diary of a Part-Time Indian by Sherman Alexie and answer the question that follows. My brain was drowning in grease.

But that makes the whole thing sound weirdo and funny, like my brain was a giant French fry, so it seems more serious and poetic and accurate to say, “I was born with water on the brain.”

Okay, so maybe that’s not a very serious way to say it, either. Maybe the whole thing is weird and funny.

But, jeez, did my mother and father and big sister and grandma and cousins and aunts and uncles think it was funny when the doctors cut open my little skull and sucked out all that extra water with some tiny vacuum?

How does the choice of a narrator affect the characterization and credibility of the text?
