07 Never use informal pronouns
If you’ve beefed up your French before visiting the country or remember it from school, the French language has different ways of saying the word “you.” It can be complicated to figure out which to use in a given situation. After all, what is the difference between, “vous,” “tu,” and “toi”? The answer is there are several. However, the most common are the formal “you” (vous) and informal “you” (tu/toi) and “vous” being used to address more than one person. Informal is when you know somebody, and so if you’re visiting France, you should use “vous” by default.
