Why did Twilly visit Mrs. Starch's house?

Twilly visited Mrs. Starch's house to find powdered cocoa and a book, which indicates that he had specific items in mind rather than a more general reason for his visit. This detail highlights his intent and purpose, which was not merely casual or social but rather focused on obtaining these particular items. The mention of both cocoa and a book suggests a narrative situation that implies Twilly had a clear plan or need that drove him to her house.

In addition, the choice to seek a book could imply a need for knowledge or information, which adds depth to his character and motivations within the story. The combination of these two elements emphasizes a practical or urgent reason for his visit, aligning with his goal-oriented nature in the context of the story.
