Xiao Ye always felt that her mother purposely wanted him to stay short so she didn't need to buy a ticket for him. The last time when they travelled by bus, he remembered that her mother hadn't bought his ticket because he was shorter than the 1.10 m mark. He started shouting at his mother for the act. He also thought that her mother did not want him to grow up so she could save money by not buying tickets for her son.
