Truman Capote said this quote

Watching her, I remembered a girl I'd known in school, a grind, Mildred Grossman. Mildred: with her moist hair and greasy spectacles, her strained fingers that dissected frogs and carried coffee to picket lines, her flat eyes that only turned toward the stars to estimate their chemical tonnage. Earth and air could not be more opposite than Mildred and Holly, yet in my head they acquired a Siamese twinship, and the thread of thought that had sewn them together ran like this: the average personality reshapes frequently, every few years even our bodies undergo a complete overhaul--desirable or not, it is a natural thing that we should change. All right, here were two people who never would. That is what Mildred Grossman had in common with Holly Golightly. They would never change because they'd been given their character too soon; which, like sudden riches, leads to a lack of proportion: the one had splurged herself into a top-heavy realist, the other a lopsided romantic. I imagined them in a restaurant of the future, Mildred still studying the menu for its nutritional values, Holly still gluttonous for everything on it. It would never be different. They would walk through life and out of it with the same determined step that took small notice of those cliffs at the left.
