Ok, I'm totally confused when you mention the knife and fork thing......and switching? Why do you switch? Or is it that I am ambidextrous, well mostly, I can write with both hands, use scissors with both hands, and although I learned to write with my left hand first, my right is more dominant in everything else....but I can cut food with either hand....mostly when in a restaurant, depending on whether I am sitting next to someone or not, if the hand I am eating with tends to bump into theirs, I just switch hands. I never noticed the knife fork thing!!
