Susan Williams went to a boarding school. Here is one of the letters she wrote to her parents from the school.

Dear Mom and Dad,

I’m afraid I have some very bad news for you. I have been very naughty and the school principal（校长）is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer.

The trouble started last night when I was smoking a cigarette in bed．This is against the rules, of course. We are not supposed to smoke at all.

As I was smoking, I heard footsteps coming towards the room. I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste-paper basket, which caught fire. There was a curtain near the waste-paper basket which caught fire, too. Soon the whole room was burning. The principal phoned for the fire department. The school is a long way from the town and by the time the fire department arrived, the whole school was in flames. Many of the girls are in the hospital.

The principal says that the fire was all my fault and you must pay for the damage. She will send you a bill for about a million dollars.

I am very sorry about this.

Much love, Susan.

P.S. None of the above is true, but I have failed my exams. I just want you to know how bad things could have been!
