Conversations with a Jap girl

I currently have a hall mate who is a Japanese girl staying 2 doors away from me.
I had a recent conversation with her that went something like this:
Me: I see you went shopping. ( pointing to the carton of mineral water and comforter she just bought)
Jap gal: Yes
Me: But it isnt really cold yet, why the big comforter?
Jap gal: No, me take taxi. ( Obviously referring to comfort cabs of Singapore)
Me: Sorry, can you tell me your name again?
Jap gal: (some unpronouncable thing) [i now know its Chikkako- because they pinned signs of our names on our doors]
Me: What university do you come from? (i regretted asking this the moment it left my mouth)
Jap gal: (Another unpronouncable thing)
Me: Do you have the new version of the internet startup CD i can borrow?
Jap gal: Huh? sorry my English not very good.
Me: Oh thats ok, my Japanese is not any good either. HAHA.
Jap gal: Ya.
