We were so wholly one I had not thought That we could die apart. I had not thought That I could move,—and you be stiff and still! That I could speak,—and you perforce be dumb! I think our heart-strings were, like warp and woof In some firm fabric, woven in and out; Your golden filaments in fair design Across my duller fibre.
As they say in the bible, that you're supposed to rejoice when people die and mourn when they're born, because it's one of the most painful acts you go through in life, is being born, and dying.
