You're so... I don't know

You're so... I don't know
You've got a smile that... I don't know
I love you truly but do you love me?
I don't know, I don't know

You're so... I can't tell
You've got a way that... I can't tell
I know I want you but do you want me?
I can't tell, I can't tell

Don't know, can't tell
What should I do?
Undecided, here's what I did
Rang your front door bell and you said:

"I don't know
Can't make my mind up, I don't know"
I know I love you but do you love me?
I don't know, I don't know

I don't know, can't tell
What should I do?
Undecided, here's what I did
Rang your front door bell and...
You said, "I don't know
Can't make my mind up, I don't know"
I know I love you but do you love me?
I don't know, I don't know
I don't know, I don't know
I don't know
