Quoi?

 - "What?" because of all the things that get lost in translation.

Here are a few of the exchanges that might amuse you:

Host Parents' Son: (upon meeting me at the train station): Est-ce que vous cherchez un taxi? (Are you looking for a taxi?)
Miki: (deer-in-headlights stare)
Host Parents' Son's Wife: (nudges husband with elbow)
HPS: Vous êtes Miki?

Guy on street: De quel pays êtes-vous? (What country are you from?)
Miki: Des Etats-Unis. (The United States)
Guy on street: Non - de quel pays êtes-vous?
Miki: Des Etats-Unis.

Host Mom: (To this day, I wonder what she said.)
Miki: Oui
Host Mom: (laughs really hard) Tu a dis oui! (You said yes!)

Miki: Nous sommes fini! (We're finished!)
California friend: (in English) Don't say that! It means we're dead!
Miki: Oh. Nous avons fini! (We finished!)

And my personal favorite:

Miki: "Quel type de films aimez-vous?" (What kinds of movies do you like?)
Guy on Train: "Quel type de femmes j'aime?" (You're asking what kinds of women I like?)
