My mother-in-law, God bless her soul had four and a half fingers on her left hand. Her ring finger having been severed near the lower phalange by an industrial steel press in an aircraft factory where she worked during, WWII.
The finger stump adorned by her wedding ring was a constant source of curiosity to any small child that was in her company. However, the story she relayed to them was not that of the gory details of the unfortunate accident, but a story to deter her little listeners in engaging in bad habits.
The tale being that she lost it when she stuck it up her nose. Yes, also slightly unpleasant, but something small children do have a habit of doing on regular occasions.
Having witnessed her telling this story many times, it never ceased to amaze me that each child's reaction was similar. A reaction of horror and bewilderment.
Yes, words are powerful if you choose the right audience.
