Dear Dad,
I'm writing to let you know about a recent development at school. A gang of students has been vandalizing school property and causing all sorts of trouble. The administration is struggling to put a stop to it.
I'm concerned because this gang is becoming more and more bold and they're starting to target students who get in their way. I've even heard rumors that they're planning to hurt someone. I don't know if that's true, but I do know that they're becoming a real menace.
I hope you can talk to the school administration and see what can be done about this situation. It's getting out of hand and something needs to be done before someone gets hurt.
Love,
Your son/daughter
