What does Montag think his feelings would be if his wife were to die? How do you know?

Montag finally begins to see his marriage for what it really is. After her near death experience (she overdoses), Montag reflects on what he might feel like if she really did die,

"He remembers thinking then that if she died, he was certain he wouldn't cry. For it would be the dying of an unknown, a street face, a newspaper image, and it was suddenly so very wrong that he had begun to cry, not at death, but at the thought of not crying at death, a silly empty man near a silly empty woman..."

Montag is finally beginning to wake up to the sad realities of the world and his personal life.
