I need to write a mean letter to someone
user
Dear [Insert name],

I am writing to express how I feel about the way you have conducted yourself in our recent interactions. You have been dishonest, disrespectful, and inconsiderate. Your behavior does not reflect what I expect from a friend, and I do not appreciate it. It is with great disappointment that I end our relationship. 

Sincerely, 
[Insert name]

Dear [Name],
I am writing to express my distain for your recent actions. Your attitude and behavior have been detrimental to the overall success of this organization, and it is time you realized that a change needs to be made.  You clearly lack respect for both your peers and superiors and need to understand that this will no longer be tolerated.  It seems that you are not invested in meeting the objectives which have been outlined, so it is with regret that I inform you of the board's decision - you are hereby terminated from this organization effective immediately.
