When you're departing Paris on the Eurostar to London, you're encouraged to buy French parfums so you can feel more Parisienne - last chance! 
Or to find your inner chat?
Go try to find the thing in the Gare du Nord or understand the signs for that matter? Has this happened to you?
The Paris Metro is another story. I love reading their signs like this one for a family ticket to the Louvre...
The Metro is a goldmine of signs... 
Regarde! A French Girl who is peut-etre perdu/lost? 
No need to worry about do not enter oneway signs if you're walking... 
Do stop and peruse the menus/ardoises dans la rue...
Why do I always come to Patisserie Secco on the day (lundi) they're closed? 
Why did they have to go and repaint the adorable dog on the wall at Secco? Dommage... 
Here's a sign I can't resist... 
Why must I read every porte-etiquette/pastry sign in every vitrine? 
You can wear Paris signs on your arm if you buy a bag at Barbara Rihl (Pierre Herme's wife) 1, rue du Juillet 75001
Or just paint directly on your sleeve like this girl in the Metro.
Moi, je t'aime PARIS SIGNS!
