Understand?

Brake lights

two guys get out

they walk back

screaming, shouting

then kicked the car.

Having got out

he hit the closest

then shouted 

''stay down''!

The other threw 

a wild punch

then he went down.

''Stay down'', he advised.

The first guy got up

then went down again.

''Stay down''! was repeated!

He got up 

went down again

as did the other guy.

What is it about

stay down

that is so difficult

to understand?
