From the first time I saw a sword fighting duel, I knew that this is what I wanted to do. I let it go for a bit, but recently when I was watching Steven universe with my twin sis, There was this character training a girl that was Steven's friend. And the question came to me, How old DO you have to be to start training for something like that. And also, how do I tell my parents that I want to do something as dangerous as that? My parents are really overprotective and I think they's freak out.
