Adamant

A stone may be warmed
caressed by the sun
but it's only a fleeting affair
the fondness they've formed
when daytime is done
will fade like the lack of despair
their imminence helped them to share

and then in the night
left cold by the moon
(reflecting it's distant ennui)
there's little delight
which means very soon
desire will dim a degree
the stone becomes hard as can be.
