My dearest [Friend's Name],

Woefully and with a heavy heart I prostrate myself before you with an emotionally flagellating letter to denounce my part in the tragic chain of events that led to the loss of your most prized possession.

The world itself mourns at the loss of your item. Know that the rest of humanity is equally devastated as I... and that none can hope to fathom the grief felt by you. 

I've let you down in the worst kind of way. Even now as I write, the guilt is immeasurable. I understand that no amount of apologies can undo what has been done. Words evade my hand as I fear there are none to truly describe how sorry I am. 

Without a doubt your treasure is completely irreplaceable and the memories you've had with it are now broken, shattered and fading.

Would that I could hope to take responsibility for this atrocity born  of my own complacency... alas I am afraid that would be futile. A futile burden that I now bear. Know that I will dedicate what's left of my pitiable body and mind to find and renew that which was so carelessly lost. 

I would not dare ask for forgiveness, only for atonement. Will you grant me the chance to make things right once more?

Sincerely,
[Your Name]
