Verse 1:
C                            Em
Oh, I can't stand another heart-ache. Though you
F                    G                     C
say you're my friend, I'm at my wits end. You say your love is
Em               F   C   Em                         F
bona fide, but that don't coincide With the things that you do,
Em             F            G
when I ask you, to be nice - you say

Chorus:
F            G           Em               Am
You gotta be cruel to be kind - in the right measure

Cruel to be kind - it's a very good sign
F         G                  Em            Am
cruel to be kind - means that I love you - Baby!

You gotta be cruel to be kind

C                     Em
Well I did my best, to understand you
F                       G
But you still mistify, I wanna know why
C                  Em             F   C   Em
I pick myself up off the ground, to have you knock me back again
                    Em                F           G
againd and again, when I ask you to explain - you say
