Dear Mom and Dad,

     I'm afraid I have some very bad news for you. I have been very naughty and the school master 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. 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. It caught fire.

     There was a curtain near the waste --paper basket. It caught fire too. Soon the whole room was

burning. The master phoned the fire brigade. The school is a long way from the town and before the fire

brigade arrived, the whole school was on fire. The master said that the fire was all my fault and I must pay

for the damage. She will send you a bill for about a million dollars.

     I'm very sorry for this.

                                                                                                                                           Much love
