((Author's note: I have made this story open to the public. I encourage people to post their own chapters and threads. If you are a potential writer want an idea of how the mirror works, read the first handful of chapters in my main thread to get an idea. You are under no obligation to make it function in the same way unless you want to, however. Have fun with it! Just make sure your chapters are in first person perspective, and you follow the rules of the site.)) I never knew my grandfather...
