When I was younger I injured myself. From the injury I hurt the muscles in my eye, Which occasionally allows my eye to "drift." Late at night, sometimes I'll see two of something, But it usually only happens when I'm very tired. I wish I could have been more tired around you. I wish I could have seen more of you, Even if it was the same moment. There could have been two of you.
But now there's none of you.
That person isn't dead, they just stopped existing.
