I have only one word that these people that you are talking about Sandfury need to learn: Research.
I've actually looked over two wikis on Slender before out of fun, and I most of the time when I see people act like this, in my head, I go, 'Dude.... That's not how he acts.'
I have a mini rage inside, because most people don't research him to know how he acts, and just takes word-of-mouth as fact.
And, as previously stated by the Lovely people above me: He. Is. FICTION.
He's not REAL, and never will be.
He's not exactly someone to be your role-model either.
Jokes I can understand to a degree, but these people.... No. Just, no.
