So open up your heart and just let it begin
Open up your heart and just let it begin
Open up your heart and just let it begin
Open up your heart
Acceptance is the key to be
To be truly free
Will you do the same for me
What Katy says to her beloved one is that he doesn't need to think of his imperfections because love is above all these imperfections like dirty laundries. So ask him to "Open up his heart and just let it begin". When you love someone you never think of imperfections and accept him or her as a whole.
