Subjects, I should get some sleep tonight, it's almost 4 AM, Slender Man still scares the crap outta me. I learned two things.
One, if you see him with more then two arms, it means he's going in for the kill. Which also means, you're toatally fucked.
Two, it is said that if you think of him, he exists.
And one more for funsies, the number one spot where you may see him is in the Black Forest in Germany...
