　　back at home, however, i am surprised to find that i mistakenly brought one of your cd home with my luggage, the one which you lent me in summer vacation when i was preparing for a music course test. i am really sorry for this and i hope no bother has been caused BECause of my mistake. i decide to send it back to you as soon as possible, so would you please send me your current mail address so that the cd can successfully reach you soon?

　　i apologize again for my carelessness, and wish to meet you again soon!

　　yours

　　liming
