There are many accents in the UK and the USA. I am, of course, a native speaker of AmE. I have trouble with some British speakers, no trouble or little trouble with others. In addition to the accent, there are differences in vocabulary. A strong Scottish accent leaves me scratching my head.
In high school I met the Morier family. The two boys and their parents had been born in Scotland, but had lived in Canada for five years. The boys spoke like Canadians/Americans. The parents could have been from Mars or the moon. The boys had to repeat to me everything they said. After five years or so, communication with the parents had improved greatly. They told me they were used to watching American movies in Scotland, so they had no trouble with understanding the American accent. In time, their Scottish accent became weaker and less pronounced.
Years ago I had to instruct an American on some subjects pertaining to Scouting. He was from somewhere in the South. Mississippi? He could understand me, but I could not understand him. Another fellow acted as our "interpreter". Crazy, but true. English friends said they had the same problem with their countrymen in certain parts of England. If you see the film "True Grit" with Matt Damon and Jeff Bridges, good luck trying to understand Bridges! You may need an interpreter. I almost did!
Gabi, great new photo! Love it!
