These Days, The Sun Slumbers

Do you remember the days when everything was great?
Those days where we had no care in the world and everyone around us didn't exist. We all danced as songs of glee flew in and out of our ears and we sang with every waking moment of the sun. Everyone knew each other and not a single name was unknown.
Some said the days would never end, but we knew they didn't mean their words.
When the sun set, we ran toward it so as to say goodbye. It always disappeared before we reached it, but I know it always saw us waving.
Do you remember how every year, we would lose one kid. They would either move away or somehow find all of our presences tiresome. Maybe they would grow ill and pass, but we would never know. At first, it wasn't bothersome because there were so many of us, so the fun never dissipated. As the years went on, we thinned out. And as the years went on, we all grew apart.
The years went on and the chase for the sun became futile. We got further and further from the sun every evening. Soon enough, there was that day we didn't even run.
Do you remember the days we decided to part way? I must have missed that part. I was too busy noticing the sun never rose back up from behind the mountains. I think, after years of chasing, we finally scared it away. It noticed that everyone is gone. We didn't. Then there was the day you left, leaving me here for my own. I had my eyes closed all day, so I didn't see you walk out of the door. I heard a creak in hinges, but I brushed it off as someone walking in. I finally opened my eyes...and here I am.

Do you remember me?
