Do you need to learn French in order to live in Paris? Nope. Nope. Nope, but let me tell you why you should. I speak French at a conversational level and hardly used it. I did this by either not talking to people, or somehow being approached by 80% of the English speaking people in Paris. Now, I will say that speaking French does open up a lot more spaces for you and allows you to feel more comfortable in the country. You will get a more immersive experience the more French that you do speak. But, like I was saying
Before you can even wonder, yes, I am trying to convince you to take off for 6 months and live some place foreign and beautiful.
