This is so sad - I hated it when Joe died. But the letter was just what Joe would have wanted to do. TBI's are hard to live with, believe me I know - I've had mine over 20 years now.

Oh, God, talk about a tearjerker. This was amazing, truly.

Excellent story, well crafted. The 'dead letter' story has been around for some time, and this is as good as any I have seen, and better than many of them.

I look forward to reading your other work.
