Summary
Analysis
Isola writes Sidney and thanks him for visiting and talking with her. She invites him back whenever he'd like. Isola also says that when she had Dawsey and Amelia over for tea yesterday, Amelia mentioned that she was sure he and Juliet were going to get married—and Isola didn't utter a word. She loves her cuckoo clock but her parrot bit the head off the bird.
Isola's letter suggests that because Sidney shared his secret with her, the two of them will be able to become great friends. Again, they met because of Juliet's interest in literature, which shows that their friendship is also rooted in literature.
