Read the excerpt below and answer the question.
SHE dwelt among the untrodden ways
Beside the springs of Dove,
A Maid whom there were none to praise
And very few to love:
A violet by a mossy stone
Half hidden from the eye!
Fair as a star, when only one
Is shining in the sky.
She lived unknown, and few could know
When Lucy ceased to be;
But she is in her grave, and, oh,
The difference to me! (Wordsworth, "She Dwelt Among the Untrodden Ways")
