a simple country schoolhouse.
a simple design.
a simple game.
a simple problem.
a simple substance.
an elementary problem in statistics.
childlike trust.
dewy-eyed innocence.
elementary, my dear Watson.
found an uncomplicated solution to the problem.
her black dress--simple to austerity.
listened in round-eyed wonder.
only the bare facts.
shocked by the mere idea.
simple mechanisms.
the simple passage of time was enough.
the simple truth.
