High the cost

I am this, the cobble stones
Hot tar between the wails and groans
Some stones are flat,our stones were round
Snap entry to the Underground
I am the pools in pavement holes
In winter frost you crack my bones
On my surface, children prance
I am the stage,I am the dance
I see you and you see me
As your peek with bended knee
I am the bricks that built your house
I am the mousehole and the mouse
Here comes Ginger, the big cat
He caught a chicken and a rat
Here the coal shed, here the lav
That is what our houses had
Cold it is if menstrual pain
Comes on in the night again
Colder still to lose your child
To the sewers wizened smile
I am the earth on which we grew
I am the mystery,I the clue
Stand on me,I am your strength
I the bowler,I the length
Golden children came to dust
I the promise,I the cost
