I was working a late-night shift at a school one night. And see, this school is basically neighbors with a church (5 min away). But I was walking around where the middle schoolers usually go. And there are windows, and one is a window that faces the other side of a wall with another window. And then some technical stuff. But I'm looking around, cleaning up messes, when I hear my name being called-- in the owner of the school's voice. But that's weird. He's not here at these hours. But I call back his name either way. But I get no answer. After a couple moments, I'm putting some papers away, and I see someone in the window. I look back and see this older man, covered in black, just staring at me. But after a moment he walks away and leaves. I thought that was the owner, but he didn't look like that. And I walk towards the window and look outside (it was open) and see no one. And it's strange because it was the middle of fall, crunchy leaves everywhere. it's concrete for the walk up to the window- and it's a rather long walk too. So now I don't want to go in there alone.
