Merle Haggard - I'll Always Know

Revenge must be the reason,
Why forgiveness was a thing I never knew.
And someday soon I know you plan to hurt me,
But don't plan on getting by with the things you do.
Cause I'll always know when you been cheating.
And I'll always know you've been untrue.
I'll always know.
Your heart is like a window,
But when I look inside I see another man.
But go on and lie and tell him how you fooled me,
But remember I saw through you're evil plan.
Cause I'll always know when you been cheating.
And I'll always know you've been untrue.
I'll always know.
And don't forget it either.
