And she smiled at me, her own sweet, tremulous smile.

She had smiled then, a smile so tremulous and sweet that it cut the heart out of him.

She stared at me, and then produced a tremulous little smile.

She managed a tremulous smile, and got the tears stopped.

Then her face brightened a little, into a tremulous smile.

She took a breath and a tremulous smile lit her face.

She gave him a rather tremulous smile, and thought thankfully that everything would be all right now.

She offered a tremulous smile, and went back into the kitchen.

She considered what he'd said, then offered a tremulous smile.

He squinted at her, and then managed a tremulous smile.
