Who's bed-time story was it?

After we got back from town, we all needed a rest. Ruth asked Grandma to read her a story before quiet time. A little while later, Daddy came in to see if Ruth was asleep and found this...Ruth was wide awake, while Grandma had dozed off. Who's bed-time story was this again?

I her own words, Ruth says "Ruthie awake but Grandma asleep, wasn't that a surprise for Daddy?"
