of rain and rainbows

The rain may fall and
Wash the smiles off children's faces.
It could wash away a lifetime's toil,
And erase any hardwork's traces.

It could even force the sun-proud day
To don a cloak of sombre grey.
But there is one thing you should always remember,
There is one thing you should never forget:

That no matter how hard it can rain,
A rainbow will always pay off the debt.
