Maybe it stems from being an English teacher/writer's kid, but I have always paid more attention to pronunciation than most people, I guess. I remember the girl next door getting mad at me when, in second grade, I tried to kindly tell her the word is church, not turch, as she pronounced it. Chimbley for chimney got the same reaction. After the buzghetti for spaghetti battle, I gave up on her pronunciation of anything.
We never discussed this at college - I went to Mass Art, where they were happy if we were literate. But one day, apropos of absolutely nothing, my Illustration teacher wrote on the chalkboard:
Bostin
Bosten
Boston
and said "Of everyone in the room, I bet Karen is the only one who would pronounce these three words differently."
One of those odd moments, where I was thinking "how could you NOT?" and everyone else was thinking "What the heck is he talking about?"
