I need to write a mean letter to someone
<|assistant|>
Dear [Name],
 
I am writing to express my deep disappointment with your recent actions. Your words and behavior towards me have been thoughtless and insensitive. Your actions show that you do not understand basic human decency and lack respect for those around you. 

You have hurt my feelings and damaged our relationship. That is why I am formally declining to associate with you any further. Please refrain from contacting me again in the future.

Sincerely, 
[Name]
