Writer's Month 2023 prompt: memories.
Dan is glad he doesn't remember the moment when the bullet smashed through the layers of his helmet then into the bone below. But it breaks his heart that Harris remembers. Remembers seeing his best friend fall like a puppet with its strings cut, seemingly dead, blood streaming down his lifeless face. Then remembers the feeling of another bullet striking his back, through the vest and tearing through muscle and organs.
At least he assumes the horrific details of the event, Harris has been rather tight lipped on the subject and the written report only dryly stated the facts. But he'd seen similar injuries, usually fatal, and it was quite easy to substitute himself into his memories and guess what Harris had seen.
It's no wonder that he wakes up in the middle of the night, screaming his name. He would do the same if their positions were reversed.
