Dear Sir or Madam:

I am writing to request your help. The fact is that from last month, I usually found some rubbish bags laid in front of my door which does not belong to me anymore. At the beginning, I assumed it must be careless mistake that somebody forgot to bring to rubbish can. I had to observe carefully since it usually appeared in front of my door from then on. I guessed it was not only just a mistake, it must be a deliberate behavior. Finally, I got the conclusion that your boy leave it every morning when he went to school. Would you please help me check the reason?

In personally, I have to say you are my good neighbor, even through the unhappy things exist. Until now, I still assume we have kept good relationship since I moved in 1 year before. I don’t know the reason why your favor boy do such kind of things against me. I will show deeply apologize to you if there are some kinds of misunderstood. If not, please help me find out the reason.

I should remind you that you are held fully responsible for your boy’s behavior. Therefore, I would be very much appreciate it if you could investigate and give me your response as soon as possible. I can be reached at 123456 in office.

Yours Sincerely
Keenle.
