《I don't know why》的歌詞如下:
I don't know why
I'm feeling so alone
When I thought I was your only one
You say you're sorry
But it's too late to apologize
Now you're gone
And I don't know why
I don't know why
I let my heart open up to you
Now I can't believe what you've done
You say you're sorry
But it's too late to apologize
Now you're gone
And I don't know why
(Chorus)
So why can't you see
What you're doing to me
How you break my heart in two
Why can't you realize
How much I need you back in my life now
I don't know why
(Verse 2)
Every night I call your name
But there's no answer now, no one home
So tell me why I feel so lost without you here now
Why can't you see the way you make me feel inside now?
(Chorus) (x2)
