A Sincere Apology for an Oversight: A Forgotten Borrowed CD

Dear Bob,

I am writing to express my sincerest apologies for forgetting to return the music CD I borrowed from you last week. It was only upon my return to Beijing yesterday that I discovered it nestled within my luggage. I must have been so engrossed in preparing for my journey that I inadvertently overlooked returning it to you.

To make amends for this lapse in memory, I have dispatched the CD back to you via express mail, accompanied by a Bob Dylan CD as a token of my apology. They should reach you within approximately a week.

Once again, I apologize for any inconvenience this may have caused. I eagerly await your reply.

Sincerely,
