What statements does the narrator make that seem unreliable?

Of course I went with Mr. Whitaker first, when he first appeared here in China Grove, taking "Pose Yourself" photos, and Stella-Rondo broke us up. Told him I was one-sided. Bigger on one side than the other, which is a deliberate, calculated falsehood: I'm the same. Stella-Rondo is exactly twelve months to the day younger than I am and for that reason she's spoiled.

But Mama just turned on her heel and flew out, furious. She ran right upstairs and hugged the baby. She believed it was adopted. Stella-Rondo hadn't done a thing but turn her against me from upstairs while I stood there helpless over the hot stove. So that made Mama, Papa-Daddy and the baby all on Stella-Rondo's side.

Our narrator is seen as unreliable because we only see her versio of the truth, and yet, she can't see past her own opinions.
