@ai6yr @grammargirl Once upon a time, we had four cats. My sister-in-law came to visit with her Border Collie. He spent the entire visit trying to herd the cats - poor thing was utterly tuckered out by the time he went home. It was a real-life demonstration! Trying and failing to remember exactly when that was, and whether I knew the phrase before the visit or just attached the phrase to my memory when I heard it.
