At work I sometimes get this sort of mail from heads of departments (its google translated):
Dear SGF,
Please review your behavior because it is ugly, annoying, offensive, aggressive and in bad taste - without ever being able to solve anything, other than a disappointing image. No one has done anything to blow you away, neither the door, nor colleagues and I hope neither do I, and if you encounter problems related to work tasks they must be solved rationally - by discussing, organizing better and not by nerves or physical force.
I appreciate you for what you do and I draw your attention to your behavior, especially since it is not the first time. It is not necessary to be all good friends, but we must have respect for colleagues and everyone's work.
What you do today will define what you will be tomorrow!
I hope you think about my message and seek to correct such issues.
Sincerely, OM
lol he still doesn't know I smashed the office phone to pieces after a conversation with him.
