Are the Swiss unfriendly?

Occasionally I'll be asked this question by people who visit or move to Switzerland and find it hard to find friends. One thing I know for sure is that if you have friends in Switzerland they are great friend and the friendships last for life (I've already lived long enough to say that, right :-)
So are the Swiss unfriendly? So far I've observed in the Swiss German parts of Switzerland that the younger generation is way more friendly and open to foreigners, new ideas and changes. The older generation likes to keep things private, thinking nowhere else except inside the box and usually isn't very friendly towards foreigners or new concepts and changes. But i think you can also find that a little everywhere.
I've also noticed that alot of the Swiss usually are good finger pointers and fault finders. And if there's something going on in the world like the US invading Iraq then they're usually unfriendly toward Americans.
But I haven't noticed them being generally unfriendly. Of course, i did grow up in Zimmerwald, a little village outside of Bern and still have a lot of friends there. When my family moved to Meilen, on the lake of Zurich, I made new friends there. The Swiss are proud of their dialect of Swiss German. And yes, I had to take alot of crap about my dialect being very different from my class mates'. But I learned to speak Züridütsch too. And I still have alot of great friends all around Zurich too.
I think that maybe when we come to a place in Switzerland where we don't speak the same language or dialect that pride of the language kicks in and that's maybe part of the trouble, at least at the beginning. But we have to try to adapt, try to speak the same, even if we suck at it. People DO open up when they see that you're trying.
By the way, that's also a general rule for if you're ever in the french speaking part of Switzerland or in France. Most french speaking Swiss also know German, actually even very well. When you go there and you try to speak german with them, they usually won't help you and aren't friendly. But if you at least try to speak french and suck at it, they usually see that you're making the effort and open up, usually they'll even proudly speak german at times if you get stuck.
In France it's alot the same. Usually you can get by by asking if they speak english the first thing you say, not a god idea though. But if you actually try to speak french with your very appearant non-french accent, doors open up and you'll probably be having a conversation in english a few minutes later. The French usually are proud english speakers too.
So I guess the biggest problem is a pride issue and if you raise the person in front of you above you, let go of some of that pride, then things get easier much quicker. Don't forget, you're in THEIR country.
