Hope(The bird in the nest and her offspring)

Tell me Love, Will the birds fly south?
or would they keep their nests this frost.
Will or won't the birds fly south?
or would the skein be deformed and lost?
Lets fly the birds away a while
lets fly the flock in hope,
the winter is too harsh to last,
for the mother and her child alone.
Pity the children know not to fly
pity the mothers sorrow,
They'll fade to the winter,
together then
they'll not see another tomorrow.

Why won't the birds fly south again,
why do they stay ?
To die in the chill of winters harsh
To bear the labour of pain.
leave behind the petty ones,
they'll cruelly be made to perish.
what survives shall only last,
what lasts, the spring will cherish.
