Elizabeth Hardwick said this quote
“ In this couple defects were multiplied, as if by a dangerous doubling; weakness fed upon itself without a counterstrength and they were trapped, defaults, mutually committed, left holes everywhere in their lives. When you read their letters to each other it is often necessary to consult the signature in order to be sure which one has done the writing. Their tone about themselves, their mood, is the fatal one of nostalgia--a passive, consuming, repetitive poetry. Sometimes one feels even its most felicitious and melodious moments are fixed, rigid in experession, and that their feelings have gradually merged with their manner, fallen under the domination of style. Even in their suffering, so deep and beyond relief, their tonal memory controls the words, shaping them into the Fitzgerald tune, always so regretful, regressive, and touched with a careful felicity. ”
