brush up on french

From Paris, my BF wrote “I went to the Orsay museum but didn’t understand much because everything was all in French.”

J’ai repondu en Francais sans traduction.

He said, “Next time, you’re coming along.”

In HS and even college, I could think in French and communicate pretty decently. Then a loooooong period went by, during which I learned smatterings of other languages. Now when I try to say something, it comes out in a mishmash of whatever terms I know best for particular words.

Now my BF’s doing business with some French dudes, but he speaks nothing but “Anglais.” I want to be the ringer who understands what they’re saying about him/us.
