You never knew...
You never knew what I was going through.
You never knew what I wanted to say to you...
You never knew I was hiding my pain from you.
You never knew I was hurt when I smile...
You never knew why I was silent...
You never knew why I sat alone...
You never knew I felt angry when you laughed at me...
You never knew I felt sad when I was leaving you...
But finally, you knew and now I am happy.
