That's all I've got Dude, so sorry for your loss...

It's a cruel joke. Man's perfect companion, the epidimy of loyalty love and adoration. Play, fight, eat, or sleep always by our side. No better friend, except... only 1 sixth of our average lifespan.
There are no words that can ease the pain you feel, only time can dull its sharp edge. But know this, the man who has never felt sorrow is a man who was never truly loved. Your pain is proof positive of his love for you, and yours for him. Now his pain is over but the love carries on.
