WHAT WAS OSCAR LIKE WHEN HE WAS A LITTLE BOY? what happened to him to cause his physical appearance to change so much? do you think this change could have been avoided-why or why not?

From the text:

In those blessed days of his youth, Oscar was something of a Casanova. One of those preschool loverboys who was always trying to kiss the girls, always coming up behind them during a merengue and giving them the pelvic pump, the first nigger to learn the perrito and the one who danced it any chance he got.

The little guy loved himself the females, had “girlfriends” galore. (He was a stout kid, heading straight to fat, but his mother kept him nice in haircuts and clothes, and before the proportions of his head changed he’d had these lovely flashing eyes and these cute-ass cheeks, visible in all his pictures.)

His physical appearance changed during early adolescence.

Over the next couple of years he grew fatter and fatter. Early adolescence hit him especially hard, scrambling his face into nothing you could call cute, splotching his skin with zits, making him self-conscious; and his interest—in Genres!—which nobody had said boo about before, suddenly became synonymous with being a loser with a capital L. Couldn’t make friends for the life of him, too dorky, too shy, and (if the kids from his neighborhood are to be believed) too weird (had a habit of using big words he had memorized only the day before). He no longer went anywhere near the girls because at best they ignored him, at worst they shrieked and called him gordo asqueroso!

For the last part of your question, adolescence affects everyone differently, can it be avoided? This calls for your opinion.
