I agree that the choppiness and lack of detail make the stories more challenging to understand. I think it's related to the way the stories were collected, i.e. they were told to educated people who were not professional story tellers, who then later wrote down what they remembered. Then the written versions were then passed on to von Schönwerth.The disgrace in The Flying Trunk seems to be the princess marrying up. From the interviews I've read with the translator, a common theme is parents not wanting to be out shown by their children.
