Richard sat on the side of the bed and looked at the floor.

She looked at the floor for a time, then raised her eyes again.

He looked at the floor; she could not see his eyes.

He thought of looking at the floor only just in time.

He opened his eyes again and found himself looking at the floor.

I looked at the floor and he was still in the same position.

Looking first at the floor, then out of the window.

I had to look away from the picture, at the floor.

She pulled her hand away and looked at the floor.

You do not have to look at the floor to know where it is.
