Dear mars, I am writing this letter to offer you my sincerest apologies for my behavior/words/actions that caused you hurt or inconvenience. I understand that my behavior was immature and it was not my intention to cause any harm or distress. I realize that my behavior may have caused a strain in our relationship, and I want to assure you that it was not my intention. I value our relationship and I regret the way that I acted. I take full responsibility for my actions and I am committed to making things right. Please accept my sincere apologies for any hurt or inconvenience that I may have caused you. I promise to make amends and do my best to ensure that this does not happen again in the future. Thank you for taking the time to read my apology. I hope that we can move past this and continue to have a positive relationship. Sincerely, Cheeku
