I Am Both Left Handed And Right Handed

I'm not ambidextrous, but I'm left and right handed depending on what it is I'm doing. I write left handedly, so when people ask I always say I'm left handed.
I use a knife and fork right handedly, but I use a spoon and fork left handedly. I remember at junior school, the dinner ladies always made sure we used knives and forks properly, so I suspect that's why I use them right handedly. When we were eating puddings, they were busy clearing away the dinner things so didn't correct us.
I brush my hair and clean my teeth mostly left handedly. I played hockey right handedly, netball right handed but I fire a shotgun left handed.
