Having read it, I am unsure what the OP wants to say. "It's a bit different in Switzerland": are you saying it's sad Switzerland hasn't turned into wherever you've been for 50 years? Is this a complaint or a compliment?

I find most Swiss to be shy, retiring which is often misinterpreted as "selfish" and "rude" by people from gregarious extrovert cultures. I have yet to meet a Swiss who was "full of themselves", which is more than can be said for a number of English speakers I have met and I've lived here for over 20 years...
