Dear Mr. Smith,

    I want to speak to you about the state of the playground.  People are throwing their garbage everywhere. They leave garbage on the ground instead of using the garbage cans.  这对孩子们来说是一件危险的事情. Yesterday, a six-year-old kid fell and cut his hand on a broken bottle. Immediately,  the boy was taken to hospital. Also, the garbage makes the playground dirty and  没有人想去那儿

    I would like you to handle this problem right away. For example,  you should buy more garbage cans and stop people from littering.

    Please take my suggestions into serious consideration. I am waiting for your answer.

Best regards!

Jerry Broker
