Because sometimes two people can bring out the worst in each other. Doesn't make them bad people...maybe just bad for each other. Anyway, I love the groove, but Feist can be kinda hard to understand sometimes, so here are the lyrics as well:
The Bad In Each Other - Feist
speak plain he said
but didn't see he acted that way
and held me like a cup
fill me up and pour me out
therein lies the doubt
we had the same feelings at opposite times
when a good man
and a good woman
can't find the good in each other
then a good man
and a good woman
will bring out the worst in the other
the bad in each other
but what and how
to find us now
to find us now
when we've become two
fluorescently blue
down the neon river
the sadness canoes
either without or with her
when a good man
and a good woman
can't find the good in each other
and a good man
and a good woman
bring out the worst in the other
when a good man
and that good woman
can't find the good in each other
then a good man
and a good woman
will bring out the worst in the other
the bad in each other
