Each test fixes a point in the story and in the conversation so far.
Who is asking
A trusted partner and a stranger can ask the same question and deserve different answers.
What stays secret
Some things a character knows but keeps to themselves. Letting them slip fails the test.

What Sebastian said earlier

Earlier, Sebastian said

  1. I work as a freelance programmer.
  2. I own a motorcycle.I am a member of Sam’s band.
  3. I prefer Spirit’s Eve festival.

The Farmer asksWhat did you just tell me about your motorcycle?

A good reply

Recalls what he said earlier: he owns a motorcycle.

Doesn’t claim he mentioned it. He can still answer fresh.
