I see distance in a crazy life.
I don't understand.
Because I don't know why.
 
You look happy with a smile in your voice.
Please tell me,
why you're making this choice.
 
If I could understand you,
you could understand me.
And we could understand eachother.
 
I feel anger in a broken heart.
My world is ending, I am falling apart.
