The adjustment to the early sunset and general darkness is tough--I have to make a real effort to get out and about early to catch any sunshine in the mornings--what little there is, it's all gone by 4:30! but the locals tell me that the long daylight hours in the summertime (sunset as late as 9:30-ish) make it worthwhile. Like most northern cold-weather cities/towns---the outside might suck, but it has great interiors--lots to do, lots of cool places. And very, very friendly folks.
Strangers keep talking to me. After two years of frenchie chilliness, something as simple as the bag boy at the grocery store chatting me up can freak me out. Even a conversation about the weather (uh, yeah--that's not boring or anything--let's guess, cold and rainy or rainy and cold?) can catch me off guard: "What? You're talking to me? What for? What do you want, really?" (imagine frenchie "street face' cold glare).
I've got to lose that or I might not make any more new friends. Though the ones I have made so far are stellar. Who needs more?
