It's even more interesting with exposure to neighboring languages. You observe more and more how they flow one into the other. Modern nationalities have introduced something of a step function feature to this, but not at all thoroughly. Americans, for one, often wonder at how many languages a European may speak. And there's significant instruction and emphasis on this, I understand. (My own experience is with the U.S. education system.) But, too, there's simply the fact that over relatively small distances -- in our modern world -- language changes. And you grow up accommodating that.
