I am cross dominant. I do somethings right handed, some things left handed, and there's a few things I can do with either. This blew the mind of every elementary school teacher I had until 4th grade because by then I had the vocabulary to explain myself.
For many years I only felt comfortable using right handed scissors in my left hand because my kindergarten teacher refused to give me a left handed pair since I write with my right hand. I argued with every adult that tried to teach me how to play baseball because I naturally line up lefty at the plate but I throw better right handed. Turns out I can bat switch but fuck them, they didn't know that.
