You had born with a defect,and that "defect" was that you were born with wings. You always got teased and bullied because of the wings. One day you moved and started going to Shiz, when you arrived there and started staring at your wings, eventually you saw a blonde girl wearing a pink dress walking up to you. Glinda: "Oh, what a peculiar one." Elphaba: "Glinda,leave them alone, they just got here."
