I think this is very true, before moving there I had so many expectations, I thought it would be easy to make friends, have a social life and get to know the city better. In the end it was easier to make friends with foreigners there than Parisians even if I am French. To me the Parisian mindset is quite cold and negative but you always find exceptions. When it comes to the city, finding a place to stay is very expensive and the standards are very low, the air is poluted and the atmosphere is quite stressful. People are much more open and welcoming in Brittany where I come from. I tried to enjoy the city as much as I could but never really did so I moved to Sweden and absolutely love it here. :)
