Oh, I'm rolling here!!! We haven't even touched the Southern Pennsylvanian or Maryland (aka Merlin) accents. My dad was born and raised in Southern Lancaster County in Pennsylvania (rather rural even now). He cheers for the Philadelphia Iggles (the football team)and thinks niny-nine is one less than 100.
When he and mom my relocated to Maryland, I was introduced to a whole new local dialect. Baltimore exists as Balmer - and yes, it's Balmer, Merlin. If you want to catch some waves, you go downy ocean. I had a whole t-shirt with the different phrases. It was like a different language!
Then my north eastern friends who want to prove that they do use all 26 letters, just not where the rest of us do - especially "R". Peter becomes Pita. Pita pawks the caw. But when the light bulb goes on, they have a bright idear. And our national's capital is Warshington, DC. Although my cousin from New York gets bright ideals.
My husband who is from India? He actually speaks better than most but has a really tough time with V's. When we first met he was talking about an upcoming trip to Whale. I thought he was going to take me to Whales. No, he was planning a ski trip to Vail. Still really nice, but not quite as exciting! We still laugh about that today. But even now, he abhors mini wans.
