Being Friends With The Slenderman

The Slenderman has always walked alone. That's the way he's been for the past few millennia, at least. Haunting different forests, killing. That's all he's ever known, until he meets Erica, a small girl lost in the forest. She doesn't react to the Slenderman any different than she would any stranger, but how will the Slenderman deal with having his meal talk to him like a human being? Especially as he's struggling to keep from killing her as she stands.
