Uh, dude, knowing one or two languages does not a genius make. Especially since if you actually wanted to read any books in 17th century France, you had to be able to speak and read Latin, and if you're from a family that wanted any kind of life for you outside farming, they probably made you study Latin when you were young. Obviously you speak French because you're French, and by the looks of it, you've got some roots in Spain, so saying it's amazing you can speak Spanish would be like saying it's amazing I know Polish.
