Once, she refused to stop talking during a lesson.
But I was prepared. There was a landline phone in the classroom (it was a special room with air-conditioning and flexi arrangements) and I had already taken her class register.
I told her that I was calling her parents. I knew she was scared of her father, so I called her father. No reply. I then called her mother.
The girl was very angry and started to yell: “I only borrow pencil what? Cannot meh? Borrow pencil only what! Cannot meh?”
When her mother picked up the phone, I heatedly informed her about her daughter’s misbehaviour. I said: “Your daughter’s attitude is very deplorable and I cannot teach her.” (你的女儿的态度很恶劣，我不可以教她)
Looking back at this event about fifteen years later, I realised that what I did was foolish. Anything done in anger is foolish. The phone call achieved nothing and further exacerbated my already rocky relations with the student.
Later on, I outgrew such tactics and learned to use more diplomatic methods with misbehaving students.
