The Linguist across the seas and the oceans

The Linguist across the seas and the oceans,
permanent Itinerant is what I've chosen.
I find myself in Big City prison, arisen from the vision of mankind.
Designed, to keep me discreetly neatly in the corner,
you'll find me with the flora and the fauna and the hardship.
Back yard is where my heart is
Still I find it hard to depart this Big City Life.
