How many times have I told them already? Is there any use? It's a problem of attitude, they don't take enough care and don't see how important it is.

Uh-huh. You can write it like this: Through profound self-examination as well as educational help from the school's leaders, I have sensed the seriousness of my mistake. Regarding this I express my most sincere apology to the school and to the teachers. Also I want to convey my heartfelt thanks to the teachers and fellow students that criticized me, reminded me and cared for me in this incident. As a full time student, I deeply love my school grounds, and through this unintentional mistake I have realized that I need to increase my awareness of safety at all times and improve my technique when playing ball. At the same time, I have felt that I should pay more attention to the effect of my words and actions on the school. I will use this lesson as a starting point to strive to become a good student who is developing in an all-round way: morally, intellectually and physically. Lastly, I again express my apologies.

Hey, how can you say that about us? This time I’m really going to follow through on what I say. Last year it was that I wasn’t aware of the seriousness of the problem. But this year it’s different. Once I’ve learned English, who knows how many good opportunities will be waiting for me. You’re just bashing our ideas. Why don’t you tell us what plans do you have then?
