I understand, I think but: what if discussion is part of the greatness involved in humankind talking languages that sometimes learns from experience too? For some people discussion is part of everyday learning and that by travelling and discussing with others you might learn better English than the crappy versions you learneth through google today. If you were to travel and not discuss then language would not be picked up and your grasp on the ongoing discussions of the English language with no doubt fail. So even if expressed in a natural way, the language that you have learned whilst travelling and using the universal translator is wrong on so many platforms and levels. So as you can appreciate the English language is complex enough to baffle and amaze even scholars like myself and I am very much used to discussion on a broader level and regularly travel many countries in an attempt to enrich my excellent language skillset.
But in essence, everyone learns from discussing things, that's what I was getting at. I hope my ramblings have not confused you as yours did me. By the way, your grasp on the English language is far better than mine on Spanish. Unfortunately for some, this is an English speaking forum.
