The girl left and the two men sat alone in the room.

He sat alone, and my heart went out to him.

Having left the bed, he sat in his office alone.

But the time went on, and the girl still sat alone at her table.

The last man on Earth sat alone in a room.

He went to where she sat alone upon her bed.

He sat alone at a table just within the door.

She came in late, sat alone at a table for two.

But a man sat alone with his back to Miles's wall.

I would have never been able to tell he was sitting alone.
