Formal letter:

Dear Director,

In last few years the school was seen in better conditions but now when it rains and you go past stepsup you can fall because the water of rain has traspased the roof and it fallas in the steps , and it's very serious problem.
Other thing that i don't like in schools is that there are railing walls and you cannot go out to walk round, it's boring.
The good things of school are that during free time or lunch time everyone can play in school made stadiums and they can eat for free (from not all cities).
I saw that in last few years our school had a nice decorations and it brought some happiness to students because in other years this school was so sad , it was only a school in gray color.
I think that students would help more to school , it would be a beautiful , and nice place to learn .
