The smile - if it had been there in the first place - was gone.
When she looked at him again, her smile was gone.
The smiles were all gone as she finally spoke again.
He looked at us, and the smile was gone instantly.
The smile was gone as if it had never been there.
Again, he looked back, only now his smile was gone.
She looked up out of the hood and the smile was gone.
The woman's smile is now gone and her eyes are blank.
The smile was gone by the time he came to stand at the foot of the bed.
The smile was gone again, and she took my hand.
