A young man had a terrible falling out with a neighbouring farmer. One night, in an act of cruel vengeance, he crept through the neighbouring fields.
As he did so, he scattered seeds of a persistent, virulent weed. Very soon, the weeds sprang up, and no amount of effort would eradicate them. Years passed, and eventually the young man fell in love with the farmer’s daughter. He married her and, at length, inherited the farm. He later confessed that he was spending the rest of his life reaping what he had sewn in that one act of angry folly.
