it takes a brave soul To tap on the wall of his cell

Where the turnkey is so discreet, 

No one ever sees him 

Making the rounds,

It takes a brave soul

To tap on the wall of his cell

When the lights are out,

Hoping to be overheard,

If not among the angels in heaven,

Then among the damned in hell.

 

[Charles Simic (Dušan Simić) {1938- } 'In This Prison of Ours', from The Lunatic]
