    I have done the bad choice and that's a good question as I have learnt many things.

    So thank you for the Creator of this QotD , for Hugo who is a good teacher and for the other posters. All of them have participated to the improvement of my knowledge.

    I was just about to correct my post being the wrong way around when I saw Hugo's correction, that is correct 🙂
