Hey guys - I've noticed there's often a lot of people wondering how to make friends in Paris. It can be tough! It's easy to feel lonely especially if you don't speak French. When I first came here I felt that way sometimes. But I found this post on Hipparis.com that helped me a lot:

It has suggestions like Jim Haynes' Sunday dinners (which I went to - it was super fun!) and going to a Franglish meeting, where French speakers practice their English and vice versa. These suggestions are great because it accepts that we're all strangers to each other before we become friends, and that we just have to push through that first phase!
When all else fails, just open up and smile, and don't be afraid to talk to people, even if you're not great at French (I barely manage myself)! Good luck!!
