What language do you speak?

This morning I had a class on countries and nationalities. And the languages that people speak. So after doing a dialog with the students it was time to do some oral with them. I asked them if they spoke a certain language and they would have to answer affirmatively or otherwise.

So I started with a student who volunteered. I asked him:
-Vous parlez français? (Do you speak French?)

He answered:
-Non, je parle malais. (No, I speak Malay.)

Then I moved on to the next student who seemed to be looking at his table. I asked him:
-Vous parlez italien? (Do you speak Italian?)

Dia angguk-angguk. Macam paham. Tapi dia tak jawab.
His friend nudged him. "Oi. Madame tanya la. Vous parlez italien tak?"
He looked up suddenly and replied, "Huh? Oui...oui...tali...tali..."

Ceh. Dia tidur rupanya.
