This is the character that everyone doesn't like.  She is a woman that sits around all day and watches T.V.  She overdosed on sleeping pills.  The impact she had on Montag's goal, was she turned him in to the firefighters.  They then burnt his house down.  She was for the system.  She kinda just followed the leader.  She followed society by doing the norm.  I really did not like Mildred because she was a very cold person.
