In "Black and Latino," by Roberto Santiago, do any of the characters change? If so, what caused them to change?

"Black and Latino" is a personal essay written by Robert Santiago and originally printed in Essence magazine. As such, it is not a story but a reflection on being born and raised with a foot in two worlds, that of his heritage, which was Puerto Rican, and that of the African American, because his skin was of a dark hue.
Santiago claims that he has a black heritage as well, since Puerto Rico is close to Haiti and states that his grandparents " . . . were the classic Negro como carbon (black as carbon) people, but despite the fact that they were as dark as can be they are officially not considered black" (1). It is in this way that Santiago discusses his growing up in East Harlem and looking black but not being accepted as African American.
Santiago narrates this essay in first person, so he is not really a character. He discusses his own childhood and one incident where he faced racial discrimination. He does not change his viewpoint on racial issues throughout this essay. Instead, he is puzzled why race issues exist at all.
