Dear Bob, I’m writing to apologize for having forgotten to return The Beatles CD to you when I left Canada. I was in such hurry that I packed everything in my luggages without checking carefully. If I have paid more attention then, I wouldn't have made such stupid a mistake. Now everything must be done to solve the problem because I understand you cherish the CD enormous. I can either send it to you by express mail or alternatively compensate you in a reasonable price. If you do not mind, I may bring it back to you next time when I go to Canada. Please let me know which solution you prefer at your earliest convenience. Felt extremely guilty, I really hope you will accept my sincerely apology.
