I am writing to apologize for causing you unavoidable discomfort. I understand that my actions have caused you to feel uncomfortable and I am deeply sorry for that.
I understand that my behavior was inappropriate and I take full responsibility for my actions. I should have been more mindful of the situation and I regret not doing so. I understand that my words and actions have had a negative impact on you and I am truly sorry for that.
I want to assure you that I will take steps to ensure that this kind of situation does not happen again. I will be more aware of my words and actions and will strive to make sure that everyone around me is comfortable. I will also take the time to reflect on my actions and learn from this experience.
I understand that my apology may not be enough to make up for the discomfort I have caused you and I apologize for that. I hope that you can find it in your heart to forgive me and I will do whatever I can to make it up to you.
Once again, I apologize for causing you unavoidable discomfort and I hope that you can forgive me.
