How do you say goodbye to a loved one you sent away to war? A person who may never have returned?
You send a message through words.
You remind the world of the man who once was.
You leave a sign, a memory that although the person has gone, some part of their actions still remain; an indelible mark.
That time, humanity or perhaps simply family would never forget them.
So this is simply a record of those farewells. See ya from the beginning until the end of time.
