The Swing Set

Everyday I head to the same playground to swing on the same swing.
There's something lurking at the park.

And there's nothing creepier than a tall man standing in the park with a huge smile on his face, staring at me. No one notices him except for me.

I'll figure out who he is, even if it kills me.

"So am I the only one who can see can see him? And why does he have a smile on his face?"
