Dear [Name],
I am writing to apologize for my recent behavior of unauthorized eavesdropping on your conversation. I understand that this was a violation of your privacy and I regret my actions.
I want to assure you that I did not mean to intrude on your private conversation. I was in the area and I heard you talking. I was curious and I was wrong for not leaving the area when I realized that I was intruding on your conversation.
I understand that my actions were wrong and I am deeply sorry for my behavior. I apologize for any distress or discomfort that I may have caused you. I have learned from this experience and I will be more mindful of other peopleĆs privacy in the future.
I hope that you can accept my apology and forgive me for my mistake. I promise to respect your privacy in the future and I will not intrude on your conversations again.
Sincerely,
[Your Name]
