A smile curved over me as he met my eyes.

She closed the eye and a small smile curved her lips.

A small smile curved the corners of his hard mouth.

She looked deep into his eyes, then a smile of delight curved her mouth.

A smile curved his lips as he dropped off to sleep.

An amused smile curved his lips before he went on.

She gave him a startled look, and a small smile curved her lips.

A slight smile curved her lips as she saw his face.

He stared at me for a long moment, then a smile curved his wide, soft mouth.

"Quite certain," and a smile curved her lips despite the tension of the moment.
