When I was a kid I was on the boardwalk at the beach, I was walking slowly so my uncle was far ahead of me with all our fishing gear. I just happened to look down at the boardwalk itself, and through the wide spaces between the wood, I see the two white eyes of this creepy looking vagrant staring back up at me, intensely. What made it scarier was that it wouldn't have been too hard for him to jab a knife or something through the spaces, or come out and up the stairs since those weren't too far away. Those stairs, of course, HAD to be between my unlce and me, making it even more terrifying. Needless to say I caught up to my uncle on the pier in a matter of seconds, I ran faster than SCP-173 moves when you blink.
