Wow! I'm so very glad your alright, DR Cillaliz! What a close call.
Your talking about cursing in car made me think about how when I was a little girl who didn't drive, my Dad would swear up a storm sometimes while driving. I always asked him, "Why do you do that Daddy?" He would grumble but never really gave me an answer.
Then I started driving and the first time someone cut me off and almost caused me to have an accident the first words out of my mouth were-&#@$!! My Dad was with me and he just started laughing and said, "Remember when you asked me why I said those things? Now you know why!"
