Since we are two

     "(...) since we are two, we know in an absolutely ineluctable way that one of us will die before the other. One of us will see the other die, one of us will live on, even if only for an instant. One of us, only one of us, will carry the death of the other—and the mourning. It is impossible that we should each survive the other (...) Yet the impossible happens, not in "objective reality," which has no say here, but in the experience of Romeo and Juliet (...) They live in turn the death of the other, for a time, the contretemps of their death. Both are in mourning—and both watch over the death of the other, upon the death of the other. Double death sentence. Romeo dies before Juliet, whom he has seen dead. They both live, outlive the death of the other."
