Great Lakes Vowel Shift

There is an unusual phenomenon few speak on. Basically, our language is changing at a high rate of speed and will be difficult to understand in coming years. A time traveller from the future would talk kind of funny compare to us. OK the reason is the Great Lakes Vowel Shift that is taking place now. This affects many northern cities in america. People in places like Chicago, where it use to be the home of our prez, well they are shifting their enunciations. Sadly, more and more words are being shifted so they do not properly pronounce.

For example, the new crowd now says "BLACK" instead of BLOCK and "BACKS" instead of BOX in order to make things harder for us. As time goes by there is a spreading of the error. It conquers new territory like a virus. This is not the first time we encounter this phenomenon because England had the Great Vowel Shift back in the middle ages. Therefore we would sound strange to the max to people of that era. A man who would time travel back would find that the people talk real funny instead of right proper.
