I looked at him and felt a smile curl my lips.

Then a slow smile curled a corner of his mouth.

A bitter little smile curled the fine lines of his mouth.

She took a step forward as an ugly smile curled her lips.

A warm smile curled a mouth that Gates found a little hard.

"I won't" A dry smile curled just the corner of his mouth.

A smile curled his lip as he leaned against the door.

A smile curled his lips, but there was no real warmth to it.

He noted the determined air about her, and a cynical smile curled his fine mouth.

A slight smile curled her lips and she held the bottle out to him.
