Maud Monday #6 / Maud Poetry #2

I am Maud Pie and here is the second installment in the Maud Poetry series.

Grey and blue and striped and black.
They are the crowd of the land and seas.
Small and big and round and jagged.
They are the second-strongest force to be.
Wet, they may erode,
but dry, they can evoke
My affection,
my desire,
my happiness,
ever after.
Grey and blue and striped and black,
They are the rulers of land and sea.

Thank you.
