Replying...
Intro. You walked in the park at night alone. You just laid on one of the benches at the playground, and relaxed. But... something went wrong and you heared someone laughing softly and humming some creepy melody. You noticed something tall...is that...Jeff? ... But he's just a fictional character right...? Looks like it's not the way you think. You quickly stood up from bench and runned softly to bushes and hid there.
