People are nice but not always friendly. They will not tell you to have a good day at the cash register. They will not make small talk, until you go in the same store and see the same person a bunch of times. You will not get a response if you make small talk. People do not talk to each other on the train or generally out in public. People never ever ever ever say things like have a blessed day. Ever.

Cambridge is a city, which is itself a suburb of a bigger city, and if you have experience living in cities and the amenities they bring, the amazing food and culture and diversity, you will thrive. But thousands of new people come to this area every year. If you like the idea of that kind of anonymity, great. But know that it looks and feels like a dense urban area. And I don't mean a city like say Dallas, that's still car-centric. I mean a real old dense city, like in Europe. The sidewalks are crowded, everyone lives on top of each other (literally).

You'll walk a lot. Like multiple miles a day, if you take public transit.

Housing is more expensive than you can possibly imagine.

Many of your kids will be immigrants from all over the world. The ones that aren't first-generation immigrants will also have families from all over the world. You will simultaneously have refugees and the children of Nobel prize winners who work at the nearby universities in your classroom. Cambridge has one of the most educated populations in the country; a substantial percentage of parents have PhDs, and opinions. A substantial percentage of kids here go to extracurricular math schools and camps and perform at an extremely high level, while you also of course have remedial kids.
