Compare Romeo and Juliet's farewell at the tomb.
I'm assuming by this question you mean how did Romeo's farewell words to Juliet differ from (or were similar to) Juliet's farewell words to Romeo. Romeo's words dwelt on her beauty - he could not believe how life-like she still appeared to be, saying her beauty had not faded even in death (of course, she wasn't really dead, just in a deep sleep from the potion she took). Juliet, on the other hand, sounds more annoyed - at first she is frustrated because Romeo didn't leave enough of his poison for her to use on herself, and even the language she uses has a harder edge - "Oh happy dagger, this is thy sheath; there rust, and let me die!" (Act V, scene iii).
