A letter is not a dialogue or even an omniscient exposition. It is a fabric of surfaces, a mask, a form as well suited to affectations as to the affections. The letter is, by its natural shape, self-justifying; it is one's own evidence, deposition, a self-serving testimony. In a letter the writer holds all the cards, controls everything about himself and about those assertions he wishes to make concerning events or the worth of others. For completely self-centered characters, the letter form is a complex and rewarding activity.
Elizabeth HardwickThe language of the younger generation has the brutality of the city and an assertion of threatening power at hand, not to come. It is military, theatrical, and at its most coherent probably a lasting repudiation of empty courtesy and bureaucratic euphemism.
