to look back on one's life is to experience the capriciousness of memory. ... the past is not static. It can be relived only in memory, and memory is a device for forgetting as well as remembering. It, too, is not immutable. It rediscovers, reinvents, reorganizes. Like a passage of prose it can be revised and repunctuated. To that extent, every autobiography is a work of fiction and every work of fiction an autobiography.
