((I'm gonna just take the 2014 stabbing case and make it to where Slenderman is real, this is just fictional for me. If you don't know about the case I'm talking about, look it up.))
You had heard about the stabbing case, which made you a little scared of making friends. You thought that like the case, with two friends trying to kill the third friend, you would get harmed by other friends too. Your parents had tried to arrange a few playdates with some of your classmates, but you would just lock yourself in the bedroom. The "playdates" lasted at least ten minutes before the kid decided to leave.
At some point, you gathered the courage to finally try going to a playground for the first time in a couple years. But everyone had heard of you and labeled you as a weirdo. You eventually ended up walking through the woods. You looked up and saw an extremely tall man with a feature-less face. He looked down at you and tilted his head.
