Write a report to the headteacher on a fight which took place in class

Start your report by saying "Dear. ___"

"I'm writing this to let you know that a fight had taken place during class, and I wish to voice my opinions about it and how you can make a difference to make sure something like this doesn't happen again, I think we can start by having a talk with  the students to understand the issues between them.__"
