How is society impersonal in Fahrenheit 451? Give a specific example that defends this fact.

I would say that Clarisse's relationship with her family
and that experience being so far from the norm is one particular example of how the
social order is impersonal.  When Montag understands the Clarisse's relationship with
her family is one of personal connection, talking, and enjoying the presence of others'
company, we fully grasp how the prevailing social order discredits human emotion.  We
also understand, to a certain extent, why Montag and Mildred are so fundamentally
distant with one another.  Resistance and active stances against social or governmental
orders can more likely be fostered in settings where individuals feel a personal stake
being threatened.  Such realities are enhanced when there is a connection between people
that is shared on an emotional level.  If there is emotional distance between people,
and a sense of isolation present in their personal lives, then there is a greater chance
that this would result in apathy and distance, substantiating the current power
structure.
