Please shut the hell up

Don't be too subtle lest your meaning fall ill, the torn
vocabulary short of reprise - to save the begotten man
a moment of monotony. She'd understand yet, whilst he
toil his way through her misgivings, courage to play a
part less heroic than before builds slowly. Would one
wait for words to fall, or precede the moment with haste
hoping for an end? He knew not. Her words count the same
repetitiously, causing ears to fail and heads to turn
about looking for escape. He closes his eyes, breath filling
his lungs, "Please shut the hell up."
