Have you ever noticed how different people in different parts of the country have a very distinctive way of talking?
Each part of our country (USA) can almost have its own unique language. Now, if you put those circumstances into effect for other countries, it is no wonder that people do not always understand what someone is talking about when they compare notes.
When I was back in high school (no, I will not tell anyone how long ago that was), I used to take the city bus to get to and from where I needed to go. I heard two men talking and getting louder and louder. One was obviously from the Bronx, the other was a deep south Cajun. They were both speaking English, but could not understand one another. I ended up translating for both of them. My bus came and I wondered what had happened.
Speaking English is no guarantee that you will communicate with others without errors.
Put in your mind all the difficulties that come about when you add in the variances from other languages in addition to the variations that happen in English.
Now, do you wonder why there are wars? No worries mate. HUHN
