Revenge, must be the reason

Why forgiveness was a thing I never knew

Someday soon, I know you plan to hurt me
          C                                     D
But don't count on gettin' back with things you do

Your heart, is like a window

When I look inside I see another man
    G                                  C
But go on and lie, tell him how you've fooled me
    C                                 D
But remember: I saw through your evil plan
