corner of somebody's mouth

He put a smile on one corner of his mouth.

When he didn't, one corner of her mouth turned up.

The smile found its way to the corner of his mouth.

Don't force it down, just in the corner of her mouth.

I saw the smile at the corner of his mouth.

Was that a smile playing at the corner of her mouth?

The men saw the blood at the corner of his mouth.

The corner of his mouth raised into a half smile.

There was a little blood at the corner of her mouth.

"Hands off," he says from the corner of his mouth as we go to her table.
