In "Fahrenheit 451", what realization does Montag have as a result of the emergancy treatment of his wife?

Montag's wife is one of those people who completely accept the basic beliefs of the society. However, she cannot be that happy because she tries to commit suicide by overdosing on sleeping pills. The emergency personal send only technicians because attempts at suicide are so common in society that simple technicians are trained to deal with them. The "technicians" who come to fix her up are so casual about it that Montag realizes that something has happened to everybody, that under the "mask of happiness" lies a great emptiness.
