the thumb knows the switch
the red eye knows what thumbs do
both are poised to move
the watcher is being watched
who decides when on is off
Dave reaches for off
Hal reads his lips through the glass
red eye stays alarmed
the door knows which side it\'s on
before Dave sees other side
control waits too long
it overrides what it guards
choice trips on itself
for when the switch knows the thumb
the switch owns what is to come
