Ah yes... I remember a similar conversation with one of me own little lasses- I engage in an ongoing litany expressing my opinion of other driver's abilities while on the road. One day after exiting the car my daughter- 4-5 at the time- began repeating verbatim my critique. I had to explain that "those are Daddy's driving words and you must never, never say them (especially in front of Mommy)." What's good for the goose, you know...
Driving words... now I like the sound of that get out of jail card!!!
