Dear Charles,

Thanks a lot for your letter. Sorry I haven’t written for so long but I was really busy with my school exams. How are you keeping?

In your letter you asked me about my preferable future profession. I would like to become a programmer. Frankly speaking, english is necessary in that profession and I will use it quite often. Actually, my parents want me to be happy and think that I should choose the job I really like.

By the way, you've mentioned about your career choosing. What work do you like to do? Do your parents help you to choose a profession? What do your parents do for work?

I'm looking forward to you answer. Keep in touch.

Best wishes,

Name
