Marco?

Two young men sneak on to a blind man's property in order to steal something of value. The blind man hears them and goes to the door with his shot gun. The two young men, seeing the blind man, stand motionless. The blind calls out, "Marco!". Silence. He tries once more, "Marco!" More silence. One more time, "Marco!"
