So, the wife has convinced herself

that the seed pods of the ornamental grass we have in the front yard are the source of the nutsedge that we've been fighting all over the front and the back yard, although there's no ornamental grass in the back. And she's out, right now, laboring to cut off all the seed pods, even though that's one of the elements that make the grass an attractive decoration over the winter and has nothing to do with the nutsedge.

She never lets little things like facts get in the way of what she wants to believe, especially if it creates unnecessary work.
