She smiled, notwithstanding her disappointment.

She's smiling because she's happy.

She smiled, and the wrinkles around her eyes crinkled with joy.

The teacher and students exchanged smiles at the beginning of class.

She couldn't suppress a smile.

She has a pleasant smile.

She was smiling madly.

He smiled with pleasure.

You have the most beautiful smile.

He welcomed us with a smile.

A smile spread across her face.

His face cracked into a smile.

She'll smile even if she's upset.

His confident smile put me at ease.

Her smile suddenly vanished from her face.
