Dear Neighbor,
I hope this letter finds you in good health and high spirits.
The main reason I am writing is to talk about an important matter. Recently, I borrowed your car, which I know is valuable to you. Unfortunately, by accident, the car was damaged. This happened in the morning when I was on my way to work and failed to notice it properly.
I sincerely regret this situation. I am willing to cover all the costs for the damage to your car. From my perspective, this matter should not affect our relationship, as I have always valued our friendship.
Thank you for your understanding, and once again, I would like to apologize for everything that happened.
Best regards,
Your neighbor
