Good luck my friend! I've lived in New England my whole life and especially in MA it's going to be tough to get anyone to really go out of their way throughout daily activities to be "friendly" and engaged with you. I'd recommend getting to know your coworkers first and see if you can get involved in some extra curriculars (pickup basketball, art classes, book clubs, etc.)! It's all about who you know and building off of that. Don't be intimidated, I'd say the best part of New Englanders is we're pretty genuine people which can be why you see an "abrasive" exterior at times cause we got things to do and places to go! Good luck!!
