Step 1: Understanding the Concept:
The question asks for the definition of the word 'indifferent' as used in the poem.
Step 2: Analyzing the Context:
The poet uses the phrase "cold, indifferent eyes." The word 'cold' suggests a lack of warmth and emotion. Paired with 'indifferent', it describes eyes that look at the poet without any feeling, interest, or care. These eyes are not necessarily hostile, but they are not welcoming or engaged either.
Step 3: Final Answer:
In this context, 'indifferent' means showing a lack of interest, concern, or care. The poet feels their beauty is wasted on people who look at them without any emotional response.
