The country is divided between Russians and Estonians, and foreigners. Estonian politics revolve around picking on Russians. It's sometimes a bit comical: Estonian schools don't have enough teachers for Estonian speakers, because of lack of planning and funding, and now they want to ban russophone schools. Russophones are forced to "learn the language" (one of the most complex in the world) while being soft-excluded from the society. Anyway, Estonians don't really enjoy speaking with less-than-fluent Estonian speakers and will switch to english or try to make humiliating corrections, so picking the language is quite hard here.
People won't hold the door if you have a kid in the arms, doctors won't be nice to you, there's absolutely no culture of service. You have systematically to send emails, calls, in-person visits to get things done, or get paid. It's not me being nice, every local will tell you the same thing we he stops pumping the "Estonia is nordic" meme (it's not, it's a post soviet society with 0 public services).
Advice: don't go to Estonia. It's no wonder one fifth of the population already left.
