a race to confession or due to desperation

there's a difference between brisk walking and a long wait at the stairwell.
a long wait at the stairwell is a race to confession subtly avoiding the risk of hysteria.
a brisk walk is a camouflaged confession, an attempt an ambush, but without the race. unfortunately this has all the room for being hysterical.

...and so goes the story, the most traumatic there was, a brisk walk, my coup de grâce.
