When you travel to country which does not speak the same language you speak, what should you do, teach all in the other country your language or learn the language of others?
If you choose to act as an invader and force your language on others, the result is resistance and chaos. If you choose out of courtesy to learn the language of everyone else you converse with uses, you show understanding and that you are willing to work with others.
Paul that is a masterpiece, I couldn't have said it better myself. Right on.
