Eek! Work have just told me they need me to go to France as part of a group delegation this summer, because I speak French and the other colleagues chosen for this trip don't. But my French is really, I mean really, rusty. I was once fluent, but have barely used it in decades.
My understanding is good enough that I can read a newspaper.
What's the best way to quickly improve my speaking? Quickly and discreetly!
