A pesky sin that's most original

A pesky sin that's most original
lives in my fumbling fingers. I miss the bulls eye
as often as I hit.  When good deeds fall
to shreds, I blush.  I rush to indemnify
a pesky sin that's most original.

The  world is always shaking.  I pause to lean
against the railing.  I sit to thread needles.
But accidents crowd my elbow.  They careen
regardless of my careful aim.  This is
a pesky sin that's most original.
