He saw the door open and a man step inside.

I saw two other men step out of the forest.

The little man stepped into the street and came toward them.

As he moved, the man stepped out of the light and was gone.

The two men looked at each other and stepped back.

The man at the door stepped quickly into the living room.

Then a man stepped forward into the space around me.

The man stepped back into the center of the room.

The young man stepped forward and held out his hand.

The man at the head of the line took a last look around and stepped inside.
