Moving abroad is always a radical change of life. It requires a rapid adjustment to a new way of life, a new language, a new culture. The stage of cultural shock is mostly inevitable.
From my experience, I experienced it in five main points.
New-York architecture was the first thing that surprised me, even if I knew how it looks like. Buildings everywhere. During my first week here, I used to walk with my head looking at the sky, with this new feeling of feeling so small. When in Paris, a six floors building is a really high one. The architecture is impressive and makes the city powerful.
Secondly, I quickly realized that I will have to deal with noise. The sirens, the klaxons, the alarms… All of these noises that art part of the city, at every hours of the day, or the night. But as for everything, we get use to it, and I now have the feeling that I am not hearing it anymore.
Thirdly, and probably inevitably for a French people, food became the main hardest adjustment to make, and it still is. From foie gras to burgers, it can be really complicated… But New-York offers such culinary diversity that makes up easily.
Finally, I discovered the American mentality, always friendly and positive. People are polite and smiling, they never complained. Which is the favorite Parisiens pastime. This atmosphere is really pleasant and enjoyable.
Globally, I think I left the most beautiful city in the world, for the most incredible city in the world.
