Safety Confines- by: unknown forgotten

This gilded brass cage in which I live
Is in the shape of a sphere
I can roll around wherever I want to
But I can't fit through the door

It's bars protect me from the wolves
And their glistening sharp teeth
The wolves protect me also
From people entering the room to take me away

I swear sometimes
That if I get it just right
Huddled in the very center of the orb
I can hear the ocean's roar

Someday I may go there
Or that's what I say
When I leave the fear and open the cage
I will run for the shore
