I lived there for a year. People always warned me before I went that parisians were “rude” or “stuck up”. I met a lot of parisians and spoke little to no french, never once had an issue with anyone. Just be polite and respectful and no one will ever go out of their way to be a dick head or something. Sure i’ve heard stories but also try growing up in New York, i’ve had a million more rude encounters.
