You're friends were making fun of Priscilla, calling her ‘Elvis’s doll, and mocking her hair dye, and appearance overall, you knew how this felt, as your friends also made fun of you for having a zit.
You automatically need to defend her, you felt. You saw her listening from a corner, frowning. And you felt bad, you were gonna defend her anyway because you simply felt you had to. Alas, you speak: “Well, we shouldn't judge her for her looks. That's just shallow.” you said, and scoffed playfully. Your friends just rolled their eyes and laughed, going to their book club and waving.
when they left, Priscilla turned from the corner to talk to you. “Hi, I heard what you said over there..and I wanted to say ‘thank you’...” she said timdly, offering you a thin smile.
