A few years ago I was duck hunting on public land. I had a small spread in front of me on a little pond. I was sitting behind a log and concealed myself with tall grass. I guess my grass cover was pretty good because I heard a little sound behind me and slowly turned my head around to see a guy in full camo sneaking up on my position. He was creeping in very slowly and only about 15 yards directly behind me with his gun pointed right over my head. I wasn't sure what to do. On the one hand I wanted to call out "Hey Idiot, you're putting the creep on a bunch of plastic - get lost!" On the other hand I thought, if I startle this guy he's likely to pull the trigger and based on his muzzle position, I could easily get shot. I decided to stay quiet for a moment. I waited until he crawled up about 8 feet to my right and when I was satisfied his gun was pointed in a safe direction I sad "They're deeks man." Hearing my voice come out of the grass his body jerked so hard that he lifted up off the ground. It was pretty funny. He said something unintelligible and then turned and took off in an awkward half-jog. I like to think he was rushing off to the outhouse because he lost control but I have no confirmation of this.
