Sir/Madam,

I am absolutely disgusted with your attitude and behaviour towards me. You have been nothing but disrespectful and unkind, and made me feel utterly degraded. Your cruelty has no place in society, and I urge you to re-evaluate your actions so that incidents like this don't keep happening.

Sincerely,
[Your Name]

You are a contemptible and detestable person. Your behavior is inexcusable and you should be ashamed of yourself. Your words are poison and your attitude is indignant and offensive. You have no respect for others or yourself, and your self-regard is deplorable. I urge you to seek help before you completely ruin any chance at making meaningful connections with people.
