Thank you again for today
Your smile saved me
Thank you again for today
Just stay there as you are
Because you cried for me
Watching you made me want to cry again
I wish that the feelings I feel through these held hands
Will always be here
You don't know you don't know
How beautiful you are
More than you'll ever know
You don't know you don't know
How beautiful you are
Because you are always beautiful
Thank you again for today
Your tears taught me
Thank you again for today
For bringing me through
As long as you keep moving forward
Watching you, I'll be encouraged again
I wish that this gentle and calm breeze
Will envelop me
You don't know you don't know
How beautiful you are
More than you'll ever know
You don't know you don't know
