That's the funny part with foreign languages, and it's even funnier when we make a little mistakes. I once wrote a paper in high school about professional careers where I said sturgeons' kids had much better chances to become sturgeons themselves. I realized what I had done 10 minutes after I gave my papere to the teacher ! lol. The funniest part of this mix-up was that, in an absurd way, it still was quite true. Sturgeon kids usually become sturgeons after all...
