The last question Clarisse asks Montag the first time they
meet in Ray Bradbury's Fahrenheit 451 is "Are you happy?". This
question is extremely important to the plot because the idea that Montag is not doing
what brings him personal satisfaction and happiness is what makes him look closer at his
life: at his job, his wife, and the norms of the society in which he
lives.
At first Montag laughs at the idea that he is not
happy, but then he looks at the way his wife has separated herself from her life, and
how distanced they have become. He cannot even remember where they
met.
On the job, Montag is horrified when the firemen burn
the house of a woman who not only refuses to leave her books, but
starts the fire that will end her life. He becomes confused. When
Beatty becomes aggressive and accusatory, Montag has a wake-up call. We learn that he
has kept a couple of books hidden himself; he reads one of his books to Mildred and her
friends; and, Mildred turns him in and Beatty arrives outside his door, to burn Montag's
house.
As Montag looks closely at the world around him,
as Clarisse taught him to do, he realizes that he cannot live
within the bounds of society and he chooses to run. Across the river, he becomes a part
of the book-readers who will rebuild society with books they have read and/or
memorized—in a place where the realization of true happiness is
possible.
