"I am not handsome, I am not interesting, I am not talented. I am not even rich. But Lise, I offer you everything I have, to the last blood corpuscle, to the last tear, everything. And, believe me, this is more than any genius can offer you because a genius needs to keep so much in store, and thus cannot offer you the whole of himself as I do. I may not achieve happiness, but I know I shall do everything to make you happy" ("Пнин").
Параллели между книгами Набокова как автокомментарии: об этом писали многие (начиная по крайней мере с Паперно и Левинтона), но это, пожалуй. мой любимый пример.
