Step-by-step explanation:
Mr. Lockwood is confused at first about the social position of Hareton Earnshaw because of his rough appearance and lack of education. Hareton works as a servant at Wuthering Heights, which is considered a lower social position compared to the other house members who belong to the upper class. The relationship between Hareton and the other house members is initially characterized by a lack of respect and mistreatment, especially from Heathcliff and Hindley. However, as the story progresses, Hareton's true identity and potential are revealed, leading to a change in their relationships.
