Are you still uncomfortable swearing in front of your parents?

I was talking to my father this evening about something I feel very passionately about and without even thinking I dropped an F-Bomb! There was an uncomfortable silence and I apologized profusely. I realized that although I am a grown woman I feel incredibly uncomfortable using curse-words around my dad. I pictured him pursing his lips and shaking his head, and imagined him coming through the phone to wrap me one.
