Uptight any-ites exist everywhere. 
Odd experiences those New Yorkers have, unless mine is the odd one. I’ve never had more of a social life - I’ve been invited to dozens of events or outings, often by people I’d just met. Of course, it takes two to tango, so if one isn’t being receptive to it…
However, it could just be because I’m from such a small, uptight town, making Seattle appear in my eyes as the social polestar of the entire universe.
To be honest, I’m not very social, and I turn down many invitations out of sheer social anxiety. Maybe some of those no-gos would have been a disaster.
Depends on your interests, I suppose, though.
I do, however, notice the mental toll the “long” winters take on some people (I haven’t noticed them, I think they’re amazingly short, but again, depends on where you’re from), mostly those who have lived here all their lives. Again, that is something that happens everywhere. Me, I love the cool rain, and the fact that cherry blossoms come into full, beautiful bloom in February!
Just throwing in a minor case for the defense to balance out some of the negative. This is all from the point of view of someone who is enchanted with the place, however; and the fact that I’ve made stronger, more tangible friendships here than I had made back home, have more to do, and enjoy the beauty of the mountains, which I’d never seen before.
Bumpkin opinion of the city, in other words.
