When examining a relationship between characters, why do you think it is important to take facts from both sides?

because the author usually writes one "true" side, while the other is "false"
because then you can pick which side you prefer, and ignore the other one
because then you can get a well-rounded, unbiased understanding of the relationship
because the characters will both view the relationship in the exact same way
