I moved to Florida 9 years ago. So 9 years in this shit hole has done away with any accent whatsoever. However, when I’m around my extended family enough, or I skype with my cousin up in Boston, or when I watch “Boston’s Finest” (best cop show ever btw…) it comes back for a few days. Last time I went up to Boston, I had the accent the whole summer. I wish it was a permanent thing, but it only appears in occasionally. Like how I say “car”, “drawer”, “harbor”, etc.
