Please be patient

Our volunteers look into many questions every day; sometimes it takes them a little while to answer.

Pro tip: you can rename the thread title with `.tr <thread name>`

Make it descriptive, including relevant context, but also to the point. This way you improve your chances of getting a more relevant and specific answer.

je voyais passer X = I saw X passing by
vaisseau à trois ponts = three-decker vessel (type of ship)

long speeches are often called "discours-fleuve". so the writer is using a metaphor.
