Ross believed in past lives. Moreover, he believed that the person you fell in love with in each life was the same person you fell in love with in the life before, and the one before that. Sometimes, you might miss her - she'd be reborn in post-World War I generation, and you wouldn't come back until the fifties. Sometimes, your paths would cross and you wouldn't recognize each other. Get it right - that is: fall madly, truly, deeply - and perhaps there'd be an eternity carved out solely for the two of you.
