Where does the creature really feel a sense of isolation?

Consider chapter 14 and the cottage family. The creature introduces this chapter as "the history of my friends"; it reveals his deep attachment to the family, and the meticulous attention he paid to every word they said. He tells Frankenstein that he transcribed the letters that Felix and Safie exchanged, and wrote down the family's story in order to remember it more exactly; it is clear that he regards the history of the world and the history of the De Laceys as being equally important. As the creature becomes more attached to the family, he becomes more aware of his isolation.
