Describe Lyddie's relationship with Triphena

Triphena works at Cutler's tavern. When Lyddie first begins working at Cutler's tavern, Triphena is a bit distant. She has her job to do, and Lyddie has her work to do. Triphena knows that Mrs. Cutler is a hard task master, and Triphena simply wants to make sure that Lyddie does what she is told. Chapter 4 has Triphena warming up to Lyddie because Lyddie proves herself an incredibly hard worker. The best illustration of Triphena's new respect for Lyddie is the story that she tells Lyddie about some frogs that fell into a pail of milk. One of the frogs "drowned right off," but the other frog kept kicking and kicking until the milk turned to butter. This allowed the frog to easily float on it. The point that Triphena is trying to make is that Lyddie is like the frog. She keeps "kicking" and working until something good happens.  
The next piece of solid evidence showing that Triphena respects and likes Lyddie is in Chapter 5. Mrs. Cutler has gone to Boston to sell the maple sugar and visit some family. Because she is gone, the workload is much lighter for Lyddie and Triphena. Triphena knows that Lyddie misses her family a lot, so Triphena encourages Lyddie to go visit her family as well. It's a huge gesture of kindness from Triphena, and Lyddie is deeply appreciative. Unfortunately, by the time Lyddie returns to Cutler's tavern, Mrs. Cutler has returned and thinks that Lyddie left without permission. Lyddie is then fired and forced to seek work elsewhere.
