I have been to Paris 3 times and I still haven't finished with all the things I wish to see there, it's just so big, and so many things to see.
What I don't like about Paris is there are simply too many people, and it can get very slimy at times, perverts bugging you, ( mainly the Arabs for my case for some reason, I don't know why since I am East Asian and we have no culture similarities with the Arabs).
Parisian is more snobbish than the other French in other provinces, even my husband thinks so and he is French.

I love the foods and the fashion products, other than that their wines taste great. I also like the architectural construction.
French doesn’t like to be approached directly with English it is better to try to learn a bit of French before going or go with a tour, you might encounter rude Parisian just due to language differences.
If you know French people it's even better to let them take you around, I prefer to go with my husband, that way, I don't encounter weirdoes and people are more polite to you.
