I might be wrong,so if I am,I'm sorry
My Dear Love,
I wish not to spend another day without you. If only I had stayed. If I had never left you I would still be the happy man I used to be, but that is no longer with us. In his place is a man who longs to see a sunny day, where all he can hear is the bird sing and the crunch of the autumn leaves. He wishes he had the blessings of the man before him, but he is glad that the man before him had only had his this new man’s experiences once, on the day he died. The sounds of bullets wizzing by his ear are forever imprinted in this man’s memory. The image of a bloody bayonet coming out of a young boy’s chest is all that he can remember. He has no passion, it died when the man’s friend was blown apart by an artillery shell. And the shouting, the crying, the wailing from injured soldiers has become too much for this man to bare. Has it only been 3 months? It feels like 4 years have gone by since the man you once knew left. I pray that this war ends soon, for winter is coming. I couldn’t imagine having to bear with the winter horrors ride with the horrors I have already endured. The only good thing I can make up in my mind is that the snow will cover up the dead bodies, so I do not have to look upon them anymore. May you be at ease always, and may the memory of the man before me stay with you forever.
