I'm left handed. I use a knife and fork the conventional way but have to swap to the left to use a spoon, otherwise I'd miss my mouth! I could never use a fork the American way for the same reason. Other than that, and for writing, I've never had much of a problem in a right handed world and I simply can't get away with left handed scissors! They are a mystery to me. My parents were very determined that I would never be forced, or even encouraged, to write with my right hand in school. They made it very clear from the start. Some parts of the world are still medieval about the use of the left hand though...
