The stressful thing about speaking French in France is that the French’s attitude towards the French language is a lot like Brit’s attitude towards English. I’ve definitely found it way more difficult than speaking German in Germany, or Spanish in Spain.
Tangential funny story: My parents used to live in Germany, and my dad dropped the car off at a local garage for servicing and the guy there spoke way better English than my dad’s German, so they conversed in English. In the time that the car was in the shop, there was a football match between England and Germany that was a big deal, to the extent that when my dad picked up the car, the guy there pretended he could only speak German.
