"One could say that the mechanism of metamorphosis is the only element of life that never changes. The journey of every individual, every country, every historical epoch—of the entire universe and all it contains—is nothing but a series of changes, at times subtle, at times deep, without which we would stand still. The moments of transition, in which something changes, constitute the backbone of all of us. Whether they are a salvation or a loss, they are moments that we tend to remember. They give a structure to our existence. Almost all the rest is oblivion."-Jhumpa Lahiri, "Teach Yourself Italian"
