No doubt you've heard of the Yellow Vest Movement (“Mouvement des Gilets Jaunes”, in French), a popular protest movement against the policies of the French government. News headlines and broadcasts around the globe have documented many well-attended and at times violent street demonstrations characterized by angry protesters wearing yellow safety vests.
Where did all those vests come from? The trunks and glove boxes of the protester's cars, that's where. Since 2008 French motorists have been legally required to keep reflective yellow safety vests in their vehicles. In case of emergency, drivers are supposed to put on their vests before exiting their vehicles. Yay socialism! Er, ahem... as the current protests target rising fuel prices (among other issues), the yellow vests make relevant and convenient uniforms for the protesters.
That, in a nutshell, explains the movement but not this dog, spied on December 1st of 2018 sashaying down a soggy Parisian street by Flickr member NightFlightToVenus. We can understand the need for protection from the rain (and last we checked, dogs can't hold umbrellas) but alas, whomever owns the red-collared canine wasn't available to provide any explanation. All's well that ends well, however: it would appear that President Macron has given in to at least some of the Yellow Vests' economic demands. As for the dog... let him eat steak!
