I am writing to express my sincere apologies for stealing from you. I understand that my actions were wrong and I regret them deeply.
I know that I have let you down and violated your trust. I am ashamed of my behavior and want to make it up to you. I know that I can never fully make up for my mistake, but I am willing to do whatever I can to make amends.
I am sorry for taking something that was not mine. I understand that stealing is wrong and I should have known better. I am sorry for not considering the consequences of my actions and for not respecting your property.
I want to assure you that I have learned from this experience and that I will never make this mistake again. I am committed to making better decisions in the future and to being more responsible.
I understand that my apology may not be enough to make up for what I have done, but I hope that you can find it in your heart to forgive me. I will do whatever I can to make it up to you and to earn back your trust.
Once again, I am sorry for stealing from you and I hope you can find it in your heart to forgive me.
