What are some quotes in Fahrenheit 451 about Mildred's laziness?

Mildred’s laziness is an example of the lack of engagement among people in Montag’s society.

In Montag’s society, people drive fast and watch a lot of television.  They do not form deep relationships with each other, and they certainly do not care much for each other.  Montag's wife Mildred is the perfect example of this.  She is lethargic and insensitive.

Mildred’s laziness is an example of the lack of engagement among people in Montag’s society.

In Montag’s society, people drive fast and watch a lot of television.  They do not form deep relationships with each other, and they certainly do not care much for each other.  Montag's wife Mildred is the perfect example of this.  She is lethargic and insensitive.

For example, every night Mildred lays in a stupor listening to her seashells.  She is completely unaware of the world around her.

The room was indeed empty. Every night the waves came in and bore her off on their great tides of sound, floating her, wide-eyed, toward morning. There had been no night in the last two years that Mildred had not swum that sea, had not gladly gone down in it for the third time. (Part I)

Montag feels disconnected from Mildred.  She is more interested in the comatose state than him.  She watches television or listens to the music.  They barely talk, and there is nothing like actual love between them.  She even tried to kill herself, but suicide attempts are common in Montag’s culture.  People see no reason to live.

Montag feels as if he has no connection to Mildred, because she is more interested in the imaginary television people than in him.

Well, wasn't there a wall between him and Mildred, when you came down to it? Literally not just one, wall but, so far, three! And expensive, too! … No matter when he came in, the walls were always talking to Mildred. (Part I)

The television is society’s way of keeping people controlled.  They are so entranced with the television people that they forget to live their own lives.  This is the way most people operate.  Books have been outlawed, but initially they were just no longer needed.  People had everything else, they did not need mental stimulation.  The government decided that thinking was dangerous.  People would be happier without it, and easier to control.

Unlike Mildred, Montag craves more.  She is perfectly happy to live with the fake families on the television and drown herself in music.  He wants to have actual interactions with people and experience the full spectrum of human emotions. It is what turns him into an outlaw.  He is curious about living with more.
