My favorite French actor happened to be doing a play when I was visiting Paris, so of course I had to go. Unfortunately for me, I completely blanked on the word "ticket" when I stepped up to the box office. It just would not come to me! I paused for a second to try to think of a workaround, and the woman running the desk switched to English and said, "you know this play is in French, right?" I was so embarrassed. But I still saw that play and it was great! Proud to say I understood about 90% of it.
