Gregor,
This story some may find funny or just stupid. My mother has been a full blown witness all her life but had a "mouth" on her. She occasionally used the word "Sh*t, Damn , or Sob.
My Father, came into the truth before they were married but never used a swear word in his life that I ever heard, and mom backed that up. When ever my mother swore my father was mortified.
One day she was in traffic.... she is a very timid driver, but some guy cut her off big time so she was royally pissed off...She proceeded to say FU and flipped him her index finger, not the middle one...the first one. Everyone in the car was in hysterical laughter!
