"Hey mister!"
Rez jumped and then slipped and then promptly fell before swiveling his head around. "Who said that?" He couldn't immediately see anyone or anything around him.
"Oh it's just me!"
It sounded like a kid, but Rez still saw nothing. "Uh, I don't know who "me" is?"
"Oh! Right! Whoopsies. Mom is always telling me not to do this. Apparently I'm scary or something."
However, Rez still didn't see anything. "Kid, I don't see you. Are you a ghost or something?" The voice erupted into giggles.
"No, mister! Nothing like that. I"m a leaf!"
