death letters

is it wrong to write a death letter? in preperation of me leaving to get deployed, ive been working on death letters to people i love and care about, knowing my luck though, ill never have to deliver them, cause if i say it, or think it, it wont happen, so hopefully that luck/unluck carries over. as a matter of opsec, i cant divulge any departure dates or locations, but if you follow the war and stuff, you'll have a good idea. well, im off to bed, just had to post this idea before i forget. thanks to all who read this, and if anything happens, and you dont get a letter, i love you too.
