You don't understand. And I can't explain.

Seems like it was yesterday when I saw your face

You told me how proud you were, but I walked away

If only I knew what I know today, ...

I would hold you in my arms, I would take the pain away

Thank you for all you've done, forgive all your mistakes

There's nothing I wouldn't do to hear your voice again

Sometimes I wanna call you but I know you won't be there

Oh, I'm sorry for blaming you

For everything I just couldn't do

And I've hurt myself by hurting you

Some days I feel broke inside but I won't admit

Sometimes I just wanna hide 'cause it's you I miss

And it's so hard to say goodbye when it comes to this, 

Would you tell me I was wrong? Would you help me understand?

Are you looking down upon me? Are you proud of who I am?

There's nothing I wouldn't do to have just one more chance

To look into your eyes and see you looking back

If I had just one more day

I would tell you how much that I've missed you

Since you've been away
