There is no one more chilling than the Slender Man. Jeff is known for his murderous tendencies and slit open mouth smile, but his face displays his intentions. You have a chance. He's not all that different from any other serial killer psychopath, hm? I'm bipolar; I'm not always in control of my own mind. Delusions of grandeur and fantasy dance under my eyelids, just waiting for me to blink. The Slender Man likes that for he likes to play. Why do you think he prefers children best? He loves their imagination. But he'll take older children and even adults if he feels they have that vital energy of a child, an imagination innocent in theory but just wild enough to see the dark depths of the world. Isn't being imprisoned by your own mind far scarier than physical imprisonment. With Jeff, he kills you but Slender Man? He plays with you like his own personal golden fiddle. When he comes for you, will he go easy, killing you outright? Or will he take his time, enjoy his prey's beautiful little cries and shrieks, their emotion-filled face and hummingbird heart? Maybe you'll disappear like Angelo Puglici? Maybe someone you love will succumb and kill you for the Slender Man. Sacrifice really does please him, you know. You should try it. Or if you're stubborn and think yourself too good for spilling blood, perhaps you could be a lure. He could always use a good lure. Or perhaps you'll stay strong, fighting against your natural instincts for self-preservation, fighting the urges and smell of berries and moist decay. Take a moment each day..can you feel the paranoia crawling up your spine, the gentle, paddling of footsteps down the hall outside the room? Maybe you're at a friend's house even? He'll find you there too, lovely. Chills fill the air, anxiety builds, and then you get up. and when you finally succumb, walking into his long, long appendages, never to return, you could be screaming internally but keep moving forward, no chance of regaining control, only able staring into faceless pale skin and keep walking, slowly, slowly, until you reach him, and then you're gone- well, to everyone else at least. Who knows what may become of you truly? Oh, the Slender Man knows. Perhaps he'll tell you before he shows you. Or maybe you'll just be gone. Can you imagine that? No God, no heaven, no reunion with mommy and daddy and grandpop and g'ma, no reward, just...nothingness. Perhaps he'll beckon to your little sister, your brother, your child as you look away for just a second, it was just a second you swear!. Or maybe it's you. He likes the special children. You're 15, you say? Perfect. He does prefer mystery. It's his weakness, really, but yours too. Death is too easy...hey..I think we've become good friends, don't you agree? I think we have...I'll tell you a secret, friend- he's there. Your computer is being tracked through your IEP and that VN won't do anything to stop him. I know you wanted to meet him, why else would you be looking him up? The ritual has been done and he's probably there by now. Not in the woods, but the yard. He made a special trip for you. Take a look outside, or better yet, go to him. Do you feel that urge to take a walk, clear your head? This was a pretty long read, after all. Your room is kind of stuffy now from all that hot breath on your neck...You think this is a joke, I'm sure, so why not do it? I dare you.

I would imagine Slender to me a gentleman with hidden intentions, slender is indeed a monster but what will you make him to be?
