Dear Bob, I am the Chinese student who lodged in your house during my stay in Canada.I am writing the letter for the purpose of offering my sincere apology to you. When I got home,I found I had forgotten to return the music CD that you were so kind to lend me.I am feeling awfully sorry for it.As I understand this CD is one of your favorites,I will do my utmost to send it to you as soon as possible.Based upon the regulations of China's Postal Services,it wll take several days to reach Canada. Please accept my heartfelt apology.I genuinely hope that you would forgive me for my carelessness. Yours truly, Zhang Wei
