I am writing to apologize for the damage I caused to your property. I understand how upsetting it must have been for you to come home and find that something you value has been damaged by my careless actions.
I am truly sorry for the trouble I have caused you. I take full responsibility for the damage and I am willing to do whatever it takes to make it right. I am willing to pay for the repairs and any other costs associated with the damage. I understand that this is not enough to make up for the inconvenience I have caused you, but I hope it will help.
I want to assure you that I have taken steps to ensure that this does not happen again. I have taken the time to reflect on my actions and understand how I could have prevented this from happening. I have also taken the time to educate myself on the proper ways to handle situations like this in the future.
Once again, I apologize for the damage I caused to your property. I understand that words are not enough to make up for the inconvenience and distress I have caused you. I hope that my willingness to take responsibility and make it right will show you that I am truly sorry for my actions.
