We speak almost every night; usually around 7 PM after she's put on her sleepwear and sits back in her recliner chair. Tonight she told me that something (can't even remember what we were talking about now; shame on me) was "finer than frog hair". I laughed. She laughed. All these old expressions fascinate me; seems they come out of her mouth now more than ever.
What will it be tomorrow? If I pay attention, there will invariably be another classic phrase.
