One person is a Japanese and the other is a non-Japanese.
The Japanese uses 「なければなりません/なくてはいけません、etc.」, the non-Japanese responds 「XXXXでは.......なくてもいいです」or 「XXXXでも......なければなりません, etc.」。
Without looking at the textbook, the Japanese and non-Japanese state 5 sentences each.
Then change your role, and state 5 sentences.
