The Slender Man is just a legend, right? I mean, this myth of a man with elongated limbs and no face who creeps around and snatches you up when you least expect is pretty goofy, right? It's not like you have to worry that he might be right behind you right now, just waiting, waiting for you to turn away from your monitor. Maybe you could check in the reflection on your screen, see if you see anything out of place over your shoulder...Actually, that might just be HIM. AAAAGGGHHH!!!
