Not addressed to whom you think

[anagramofbrat]

Stuck in my head today:

This prison has now become your home
A sentence you seem prepared to pay
It took a day to build the city
As I returned across the lands I'd known
I recognized the fields where I'd once played
I had to stop in my tracks for fear
Of walking on the mines I'd laid

And if I built this fortress around your heart
Encircled you in trenches and barbed wire
Then let me build a bridge
For I cannot fill the chasm
And let me set the battlements on fire
