    State a function, use an analogy and answer two clarification questions.

    It looks like a small notebook, but it can display a whole library. Think of it as a shelf whose books appear when selected. Let me show you what changes and what stays the same.

Role A

You have invented a notebook that can display any one of your documents. Explain the fictional function without claiming it is real technology.

Role B

You are interested but sceptical. Ask about size, operation and the limits of the comparison.

Check your conversation

  • Use an accessible comparison and name its limit.
  • Ask and answer two clarification questions.
  • Use three target items and revise an initial assumption.

Try again: Repeat the final interaction once. Improve one expression and one response to your partner.
