Read the passage from "two kinds.”

and then i saw what seemed to be the prodigy side of me—because i had never seen that face before. i looked at my reflection, blinking so i could see more clearly. the girl staring back at me was angry, powerful. this girl and i were the same. i had new thoughts, willful thoughts, or rather thoughts filled with lots of won'ts. i won't let her change me, i promised myself. i won't be what i'm not.
