Comic on how Jeff met Slendy, mostly inspired by this 'Ask' question - [link]
If you haven't read the description here's the little story I wrote:
This is how Slenderman met Jeff, like Slendy said it was about two years after Jeff went insane. Jeff was 15 and trying to find out different methods to kill people. He was stalking someone near the woods, but he wasn't good at sneaking. Slenderman happened to be passing by saw Jeff, observed him for a while, and then shouted "YER DOIN' IT WRONG!"
And then later Slenderman took an interest and taught Jeff a few things, and they became friends (kind of a love-hate relationship)
I tried to make Jeff look younger, wasn't easy. His eyes are larger and his hoodie is just slightly oversized, and the knife looks larger because he himself is a little smaller. Or it might just be a bread knife instead of a butcher knife.
Oh, and don't give me crap about 'your version' of how they met, this is my version with my variants of the characters, if you imagine it differently then good for you; this is my version.
