Wife of Montag
We can tell that Mildred is a normally tired person by how her actions are shown in Fahrenheit 451. For example, in Chapter 1 it is stated," Her face was like a snow-covered island upon which rain might fall, but it felt no rain; over which clouds might pass their moving shadows, but she felt no shadow." This explains her tiredness because she took too many sleeping pills,and that's why she is in that state. Also, she is constantly talking about not remembering things adn forgetting bita of important informaation. Forgetting importan things has been proven as a side-effecet of lack of sleep.
Mildred was directly characterized as skilled. One example of this was when Montag discovered her in the kitchen and the following quote was stated: "She was an expert at lip reading from ten years of apprenticeship at Seashell ear thimbles." This is an example of direct characterization of Mildred because it specifically explains something about her. This statement describes Mildred to the readers without them having to gather information for themselves.
