Nothing out of the ordinary happened. Other than Him being around children in the park, things have been pretty good. Although, I doubt things will be good for those children in the near future. I mean they just met what others call the Slender Man. This is probably not the last time they are going to meet Him.
Oh, about that. He just stood there, right near the children as they played around him, and then he just disappeared. He was there one second and the next gone. Not even a poof. Some of the children looked bewildered but they continued with their play. Afterward, the parents came to pick up the children.
