Have I ever really known the full me? Not necessarily. She is but an aggregation of all the experiences she's ever had, people she's ever met, memories she's ever made, even the ones that have been lost to time.
My personality, speech, and mannerisms are all imprints made by passersby.
Need I know the full me? No, not necessarily. Like stained glass that misses the details, I am a mosaic known only in concept and suggestion, and this is enough as inhabitant of this body, even if the resident is unknown to self.
