Guy Montag works as a fireman, which at the time meant that he burned books. He likes his job and sees the kerosene smell that surrounds him as a kind of perfume. When he comes home after work, he feels lonely. His wife Mildred wants to be entertained 24 hours a day and therefore has a small radio permanently in her ear and the three TVs in the apartment are also on all day.

Well, an internal conflict is when a character struggles in their mind and heart over a decision. An example could be; someone struggling over to make the right or wrong decision, like saving a book or burning a book, killing a spider or setting it free, helping someone carry boxes or leave them to do it themselves, etc.
