Was my French any good?
Let me see that...
Je ne parle pas. Je parle japonais, et vous?
Let's try to correct it, shall we?
"Je ne parle pas le français" (you have to put "le français" again here, otherwise it only means "I don't speak"). But the rest is good.
Wow dude, you speak Japanese, that's awesome! I speak some Japanese too: konnichiwa, watashi wa Ghisy desu. Watashi wa Furansu-jin desu. Anata wa America-jin desu ka?
Au universite etude tous deux en meme semestre, annee, mais mieux a le japonais.
"A l'université, j'étudie les deux langues dans le/la même semestre/année (what do you mean there? I'm lost) mais ... (ok i'm lost again here, I'm not sure what you mean? you like Japanese better? or you're better at Japanese than French?)
And yes Joey, only kinda (only when I have to, which is everyday here...*sigh*)
