Kristine and Pei Zhi

Kristine likes to show her authority whenever she is with PeiZhi who is 2 years younger than her.

On one instance, PeiZhi was sitting on her chair (Her mum bought for her).
Kristine went up to her and said: "You stand up."
PeiZhi stood up and looked at Kristine Jie Jie
Kristine sat down on the chair and said, "I am bigger than you so you must let me have the seat."

Yi Yi told her off, telling her not to bully peiZhi.
Kristine retorted that, "Who ask her not to fight back."
