Skeleton Graveyard

Dear Death,
I met your friend.
It was late at night, and I decided to pass through the graveyard. There was this rumor at my school where this kid had thought he had seen some kind of 'creature' walking through there. I wanted to check it out and see if it was real. I had never really believed in the supernatural.
Now that I think about it, my cat and some of the dogs in the neighborhood had been missing.

I shoved open the creaky wooden gate and slipped inside, keeping my eyes peeled. At first, I saw nothing. But as everything quieted down to just my breathing, I saw another being sitting on a nearby gravestone, chewing something. As I got closer, I smelled something rancid like rotting meat. I got suddenly scared, so I started to back away, but my foot crunched on a twig. The skeleton looked up at me from his meal. I felt paralyzed as he hobbled his way over to me and placed a cold, wet, bloody bone hand on my cheek. That was the first time I had met my best friend.

I snuck out every night to see him in the graveyards. He could never leave the graveyards, and he enjoyed my company. We had so many conversations, about my family, my life, and the things I wanted to be. He never talked about himself, but I would notice sometimes when I was talking about my family, that he would get a sad look his eyes. Well, not that he had much of eyes, but you could tell by the way of his head posture how he felt. I talked to him out loud, but he communicated through actions. I had once brought a note pad, thinking he could write on it, but when I handed it to him, his hands, like they had bone arthritis, would not do the things he wanted. So we remained this way. It was a happy time.

It was only three days ago, while I was sitting in my boring math class, that I realized I loved him.
I'm going to tell him tonight.

See, over there! He's waiting for me!
What's that shiny thing he's holding?

Why am I in a concrete box?
