Dear TOM,I would take this opportunity to express my deepest apology concerning about my mistake.As soon as I arrived at home, I found a music CD in my luggage that borrowed from you. The reason why this awful incident should happen lies in the following two respects. First, I am so harry to catch the plane toChina. Secondly, I forgot it in the luggage and did not remember to take out.(考满分作文网-WWW.SANWEN.COM)I want to leave the CD as the memaries of visitingCanadaand send you a new one bought from the Taobao.Your kind and thoughtful acceptance of my apology is highly appreciated. I would do whatever necessary to make up for the loss.Sincerely yours,Li Ming
