Answer :
In the given passage from T.S. Eliot's "The Love Song of J. Alfred Prufrock," the two sets of lines that suggest the speaker is concerned about how he relates to others are:
1. "To prepare a face to meet the faces that you meet" - This line indicates a sense of unease or anxiety about how the speaker presents himself to others. It implies a need to put on a facade or mask when interacting with people, highlighting a concern about social interactions and perceptions.
2. "In the room the women come and go
Talking of Michelangelo" - This set of lines suggests the speaker's awareness of the superficial or trivial nature of social conversations. The mention of women discussing Michelangelo while the speaker contemplates deeper questions like "Do I dare disturb the universe?" reflects a disconnect between the speaker's internal thoughts and external social interactions, indicating a struggle with how he fits in or communicates with others.
These two sets of lines emphasize the speaker's inner turmoil, self-consciousness, and introspection regarding his relationships and interactions with others, portraying a sense of isolation and alienation in social settings.
