daily practice (1)

You have seen a man a few days ago in your local park, causing damage. Write a letter to the park management and say
- What did you see?
- Who are you?
- What do you think should be done about it?
Mr./Mrs.
Last weekend, I saw a middle-aged man in a red coat who managed to break in a fence in your park. The damage he did is still clearly there, which is a stain to on the beauty of this public place.
I am a college student from Normal University of Beijing. This park is my favorite relaxing place to relax during my free time; I often hung hang out with a few school friends here.
In my opinion, such activities should be polished punished, otherwise there would be more happened in the future. More stuff things* is are needed to secure the public facilities in the park, especially during weekends and holidays when there are much more visitors here.

Sincerely,
Wang

* stuff refers more to objects. I nthis case the most typical expression would be 'more precautions'.

The sentence I liked best is 'I often hang out with a few school friends here.`- sounds very natural, perfect application of the verb.
