I would start by asking why you even asked this question, lol. But I am here to be the expert anyway. Just don’t reveal that I helped you do this! Here is how you write a letter to make someone feel guilty:
- You can start the letter with dear, but that alone is kind of kind. Say dear bully, mean guy, or dear rude individual. Lol.
-Why are you trying to make them feel guilty? You have to depict the scenario as if the person hurt you, your feelings, or someone you may know. Play heavily on their emotions.
- Who is the person you are trying to make feel guilty? Is it a bully, friend, frenemie, old friend, relative , or coworker.
- Understand the art of persuasion, which I would say requires more research and reading literature.
I hope this answered your question, and Happy New Years Eve!
