The significance of this quote is Montag's realization of what his job is actually about and what it implies. He became a fireman because he was meant to. However, he is now haunted by this new feeling and does not know anymore what is right and what is wrong.
It isn't simile, because there is no comparison to anything, and it isn't ironic.
The lines in the excerpt from The Scarlet Letter by Nathaniel Hawthorne that are examples of metaphor are:
<span>"A good man's prayers are golden recompense!" rejoined old Roger Chillingworth, as he took his leave. "Yea, they are the current gold coin of the New Jerusalem, with the King's own mint mark on them!"</span>
is it like first person point of view or man vs himself??
