Huh? Who's there? Dog at the front door barking at the air. Wind all "woosh" in the trees. Then, "chk chk chk chk" feet on leaves. Uh, it's probably a cat. Might be a guy with an axe. Might be a trap. Shit, it's probably a trap. Might be a possum in the trash. It's probably a trap. "Aye, keep it moving." God, I sound stupid. Good chance I'm not even talking to a human. Then again it's probably a trap, somebody had to set it. Depending on the type, maybe several.
