Step-by-step explanation:
The letter could contain some ideas such as the following:
Mr. Principal;
Best regard; I am glad that you are well, I am writing you this letter to mention two things that concern me a lot; First, the treatment or behavior that I have noticed among the students, they attack each other, say bad words and do not treat each other with respect. That is why I consider that social coexistence activities are carried out more often that allow them to interact with each other.
I also consider it convenient for teachers to have more social interaction and communication, as well as extracurricular activities between them that allow them to get to know each other more and work together on new projects to continue helping students in their integral development.
I really appreciate your attention, have an excellent weekend.
