823 Don't malke fun of me just because I'm Japanese!
825 How persistent!
828 What a waste of time!
830 Can you pay me back the money I lent you to buy the Coke?
831 Can you be quicker?
832 I was 30 minutes late. You were not there already.
834 In a word,I don't like it.
835 Actually I haven't studied English a lot recently, so I can't speak it as well as I used to.
836 Oh, you speak Japanese well!
837 Could you say that again?
838 Could you speak louder and more clearly?
839 Sorry, what did you say?
840 I don't understand what you said. Could you speak more slowly?
841 Pardon?
842 I can't express my feelings in English and you don't understand Japanese,but I'd like to talk some more with you.
