What are you doing, Tom?
I'm writing to my mother.
But you wrote to her only yesterday.
Yes, but I have something new to tell her.
Something new?
Yes. I am telling her I've decided to take up a part-time job as a shop assistant.
What do you mean? You've been working at one nearly three months. Have you been fired by Rogers?
No. My mother doesn't know I have a part-time job.
You mean you didn't tell her before?
No. I didn't want her to worry about my study.
But why are you telling her now?
I don't want her to worry about my life here. You see, I told her that I'd just bought a car in my letter.
