DIALOGUE

Practice by reading the dialogue with your tutor. After you are done, switch roles and do it again.

  • Kevin: Do you agree or disagree with the following statement? There are more impolite people than polite polite.
  • Dorothy: In my opinion, some people are unkind and impolite, but most people are pleasant and respectful.
  • Kevin: That’s an interesting view. Sometimes I meet unfriendly, impolite people who make me disagree with that idea.
  • Dorothy: Oh, that’s a shame. It’s unfair to let a few bad eggs to ruin your impression of everyone else!
