Dear Bob,
I am writing to express my apology to you. Several days ago, I borrowed your music CD when I lived in your house. Unfortunately, after I came back from Canada, I found it in my luggage. I was in such a hurry that I forgot to return it to you 。I will send it to you by post or express as soon Sincerely yours,
end our maintainers to go to your home for maintain services next Monday .
Best regards!
Wang Hao Manager
