Because she lied to her mother
Because her classmate fought with her
Because she fell from the bicycle
Because she was angry from her classmate
Because she liked the sound of popping a balloon
She did it by mistake.
Because she did not pay the fees.
Because she was caught stealing.
Because she barged into the school and shouted at the principal.
She was hesitant and did not know how her mother would react.
She did not feel like talking to her mother.
She enjoyed lying.
