"'Are you happy?' She said." (Bradbury 10) - This is when Guy Montag's neighbor is making him question what he always thought was obvious.
"Montag said, 'It's only a step from not going to work today or not working tomorrow, to not working at the frehouse ever again.'" (Bradbury 64) - After setting ablaze a house with the owner still inside he feels regret and he does not want to do that again.
"'Nobody listens any more. I can't talk to the walls because they're yelling at me. I can't talk to my wife; she listens to the walls. I just want someone to hear what I have to say.
