When I tie a knot, It stays tied
"So if the evil he done wasn’t the death of the roaches, what was it? The power he had? His knack for making things go just where he wanted, making them break just in the right place, understanding how things ought to be and helping them get that way? He’d found that right useful, as he made and fixed the things a boy makes and fixes in a rough country household. He could fit the two pieces of a broken hoe handle, fit them so tight that they joined forever without glue or tack. Or two pieces of torn leather, he didn’t even have to stitch them; and when he tied a knot in string or rope, it stayed tied. It was the same knack he used with the roaches. Making them understand how things was supposed to be, and then they did what he wanted. Was that his sin, that knack of his?"
