I've heard it said what you don't know won't make you blue But somehow with these words I can agree Cause it's not the things I know you do that breaks my heart you see It's the things that I don't know that's killing me I don't see you when you meet him secretly But I think your arms have held him tenderly So it's not the things I know you do that breaks my heart you see It's the things that I don't know that's killing me [ steel - guitar ] The little things that you don't notice hurts me so Little things no one but me could ever know I will keep them hidden so no one can ever see It's the things that I don't know that's killing me I don't see you...
