Areply to christopher marlowe`s "the passionate shepherd to his love".

if all the world and love were young,
and truth in every shepherd`s tongue,
these pretty pleasures might me move
to live with thee and be thy love.

but time drives flocks from field to fold; 5
when rivers rage and rocks grow cold;
and philomel becometh dumb;
the rest complains of cares to come.

the flowers do fade, and wanton fields
to wayward winter reckoning yields: 10
a honey tongue, a heart of gall,
is fancy`s spring, but sorrow`s fall.

thy gowns, thy shoes, thy beds of roses,
thy cap, thy kirtle, and thy posies,
soon break, soon wither - soon forgotten,15
in folly ripe, in reason rotten.

thy belt of straw and ivy - buds,
thy coral clasps and amber studs, -
all these in me no means can move
to come to thee and be thy love.20

but could youth last, and love still breed,
had joys no date, nor age no need,
then these delights my mind might move
to live with thee and be thy love.

what is the theme of this poem?
a) life is better when you are old.
b) the shepherd is nice to his love.

d) people often lie to get what they want.
