I’m sorry you are dealing with this. Anytime I have a student disrupting our success, I speak with them privately to ask what is going on. I also call parents and ask what is happening. Emails are not as effective as a phone call. Usually when I speak to a parent, the problems resolve much quicker than a back and forth email chain.

I then tell the student very politely and in an encouraging tone that the band (students and staff) will remember your legacy one of two ways: either helping or hurting the progress. While you may not care now, you will if you ever decide to return and visit. It will be 100% clear to you then how your legacy was remembered. I tell them I want them to leave a positive legacy and ask them to let me help them do so.

We rarely have these issues. They usually occur in my career with new jobs and those type of students quickly change or leave.
