Dear [Name],
I am writing this letter to apologize for my greediness. I know that my actions have caused you pain and I am deeply sorry for that.
I understand that my greediness has been a source of distress for you and I want to take full responsibility for my actions. I have been selfish and have not taken into consideration how my behavior has affected you. I should have been more mindful of your feelings and I apologize for not being so.
I have taken some time to reflect on my actions and I now realize that my greediness was wrong. I understand that it was not fair to you and I am sorry for not being more considerate. I understand that my actions have caused you a lot of stress and I want to make it up to you.
I am committed to changing my behavior and I will do my best to be more mindful of your feelings in the future. I will try to be more considerate and take into account how my actions might affect you. I am also willing to do whatever it takes to make it up to you and I hope that you can forgive me for my greediness.
Once again, I apologize for my greediness and I want to assure you that it will not happen again. I am truly sorry for the pain that I have caused you and I hope that you can find it in your heart to forgive me.
Sincerely,
[Your Name]
