The title does not refer to Senator Elizabeth Warren but to a different persistess altogether. She and the birthday girl's younger brother were playing hide and seek. When she went home, she thought she had all the pieces they had been hiding but she was wrong. She had just gotten that set of Lego pieces and she already lost one! To replace a missing piece was almost as expensive as buying the whole set. If she was older, she might have muttered some naughty words. She was downhearted and upset.
Both of her greatgrandparents looked carefully to see if they could find the missing piece. Everyone agreed that it was somewhere in that room. How about under the piano? How about in the trash can? Grandad went outside with a flashlight to see if it had been dropped on the way to the car. Nope. Not there and not there, either.
Could she come over and search the room for herself? Yes. Her mother and father drove her back to the room. Grandad was confident she would not find anything that parents and greatgrandparents hadn't. He bet her one American greenback that the missing piece would not be found. How could a ten year old find something that experienced searchers many times her age couldn't find? Not only couldn't find, but also doubted it existed.
Well, you know what happened? The searchers had not thought of expanding the collapsible plastic sphere to see if the missing piece had be put into its center. But the little hider thought of where she had hidden the piece, expanded the sphere, and as the French say:"Voila!" Grandad is now out one genuine American greenback and the little hider has proved her persistence, her ingenuity and her memory.
