The
person who is best suited to us is not the person who shares our every taste
(he or she doesn’t exist), but the person who can negotiate differences in
taste intelligently — the person who is good at disagreement. Rather than some
notional idea of perfect complementarity, it is the capacity to tolerate
differences with generosity that is the true marker of the “not overly wrong”
person. Compatibility is an achievement of love; it must not be its
precondition.
-- Alain de
Botton on his essay about why we will marry the wrong person.
