I am writing to express my sincere apologies for the prideful behaviour I displayed to you recently. I understand that my behavior was unacceptable and I want to take this opportunity to apologize for my actions.
I understand that my pride was unwarranted and I should have been more humble and understanding. I take full responsibility for my behavior and I regret that it caused you any distress. I understand that my pride was not only disrespectful to you, but also to the situation.
I have taken the time to reflect on my behavior and I now realize that my prideful attitude was not only inappropriate, but also hurtful to you. I am deeply sorry and I want to make it up to you. I understand that words are not enough and I am willing to take whatever steps necessary to make amends and to ensure that this behavior does not happen again.
I am aware that my pride was inappropriate and I am committed to changing my attitude and behavior. I am also committed to learning from this experience and to becoming a better person. I will strive to be more humble and understanding in the future and to be more mindful of how my actions affect others.
Once again, I apologize and I hope that you can forgive me. I understand that it will take time to rebuild your trust and I am willing to do whatever it takes to make it up to you.
