No, wow! Don't be sorry, this is awesome and exactly the type of interaction I am looking for, not just because it was positive but because it is well expressed. The two first replies I got from this post are exactly and precisely the type of formulation I am looking for, well expressed. Muchas gracias por tomarte el tiempo de decir lo que tienes a decir, eso es, precisiamente, lo que me permite avanzar a retroceder de la manera adecuada.
