what?

Have you ever thought you speak a language well and found out you are totally wrong?  Oh yes, some people might think I speak English.  Well if you do, you are wrong.  Some person on the street stopped me to say something.  First off, people from England don't acknowledge your existence while walking, so I was shocked that someone was actually looking at me.  And not only that, speaking to me.  The problem arose when I could tell he was speaking English.  Yet, I could not understand more than a word he was saying.  I am all for accents, but there comes a time when you are speaking another language.  And this guy clearly was.  I had no idea what he was saying, his English-English accent was extremely heavy.  I heard something about a bag something something.  I said 'excuse me?' and he repeated himself.  I said 'sorry, I have to go' and walked so fast out of there, I was almost running.  It didn't help I was carrying the camera and I felt extremely paranoid.  So if you ever travel through England and think you'll understand what they are saying.  You might be right in most places, like cities.  But don't be surprised if your English doesn't get you far.
