What did Malala do to her friend Safina, and how did it impact the rest of her life?

Malala suspected that Safina was stealing her toys, so she started stealing from Safina in return, something that she could not stop. After getting caught, Malala was devastated by the disappointed of her parents, the fact that she brought shame upon her family with her actions. Since that day..... Malala has not lied or stolen. She even stopped wearing jewelry.

"What are these baubble which tempt me? Why should I lose my character for a few metal trinkets?"
