I spent three years in the early 90s in the US Army, with my Basic Training in Ft. Leonard Wood, Missouri. People from all over the country converged on the post, bringing their accents with them, of course.
Being raised in the heart of the Midwest and only traveling occasionally to Chicago for family purposes, my exposure to accents and dialects was rather limited, as you might imagine. Watching movies and TV was really my only experience with the diversity of American English language outside my 500 mile corridor I occasionally traveled as a child.
One of the very first things any new soldier did was learn where everybody else came from. Since nearly everybody was fresh out of high school, we also discussed class sizes to see who came from the smallest or the largest. I was certainly on the smaller end of the scale, BTW. Oddly, being from the Midwest, some people thought it funny to ask if I drove a combine to school.
Anyway, one of the soldiers near me was from the Boston area and had the accent to prove it. We all got a kick of how he spoke and he seemed to take it in stride, I guess. One day, he and others were talking about something during our downtime but I was not paying attention. By then, we all knew where we everybody was from and apparently the discussion was about horses, at least briefly. The Boston soldier called out to me and asked, me being from a Midwest state, if we had any "hosses" there.
Like I said, I was not paying attention to the conversion among the handful of soldiers in the room so I thought for a few seconds and replied with: Yeah, we have hosses, but I only know of one but his real name is ____ ____" (name omitted since not important). Keep in mind it was the Boston guy who asked me this and I did not know the context of the question. In my small town, there was one guy known to others as "Hoss". I don't know if I learned his real name until several years into my childhood, even though he lived about six houses from me but everybody just called him "Hoss".
Everybody in the group looked at me with a confused stare until one other person said (in a decidedly non-Boston accent) "Uh... I think he meant "horses".
