Grime on the kitchen tiles

There is grime on the kitchen tiles
It is dark and presumptuous
Inexorable and dense
Marring my kitchen, my hearth
My father told me to not
Consider it as a worthy adversary
That with a chemical concoction
And effort and ambition
It would go away

But I argue and tell him
That it could go away today
If I tried hard enough
But it will come back again
My mother then told me that
Though it is insolent and stubborn
You would have learnt by then
By routine, foresight and hope
How to scrub it all away
