Use the excerpt from “Ghost House” by Robert Frost to answer the question. Which lines from the poem do jog help develop the theme?

I dwell in a lonely house I know
The woods come back to the mowing field
The whippoolwill is coming to shout
They are tireless folk, but slow and sad
With none among them that ever sings
