Angela Carter said this quote

Those were her best days, although there was always something feckless about her, something so slack and almost fearful in her too frequent smile, so that when you saw Mignon being happy, you always thought: It can't last. She had the febrile gaiety of a being without a past, without a present, yet she existed thus, without memory or history, only because her past was too bleak to think of and her future too terrible to contemplate; she was the broken blossom of the present tense.
