Dear Mrs. White,
I just learned from my son the terrible news that my dog had crimbed over the fence and destroyed the flowers in your backyard garden.I feel awfully sorry after hearing about this bad news. I know that Mr. White is trying the increase the height of the fence. I apologize for what you have to do to prevent the dog from climbing over again in the future. I'd like to schedule a meeting with you at your earliest convience to discuss how can I compensate for the loss. I know that not everything can be compensated for by money. Your effort and time in maintaining the garden cannot be measured in terms of money. For that, please accept my sincere and deepest apology.
I'm looking forward to hearing from you and meeting with you soon.
Best regards,
Mary
