The Universe of Discourse consists of John and Mary on opposite sides of a closed door.

1. JOHN is OUT, MARY is IN, the DOOR is SHUT.
2. JOHN can see, MARY cannot.
3. JOHN BELIEVES that if you move, nothing changes. MARY BELIEVES that if you move, and the door is open, you change position.
4. JOHN has the goal of getting IN. MARY has no goals.
 

1. JOHN: Mary.
2. MARY: YES.
3. JOHN: I want to suggest a Goal.
4. MARY: GO AHEAD.
5. JOHN: Will you help me get in?
6. MARY: BY ALL MEANS.
7. JOHN: Shall we make a plan?
8. MARY: JOHN.
9. JOHN: Yes.
10. MARY: MAY I ASK YOU SOMETHING?
11. JOHN: Go ahead.
12. MARY: ARE YOU IN?
13. JOHN: No.
14. MARY: SHALL WE MAKE A PLAN?
15. JOHN: OK.
16. MARY: JOHN
17. JOHN: Yes.
18. MARY: MAY I ASK YOU SOMETHING?
19. JOHN: Go ahead.
20. MARY: CAN YOU MOVE?
21. JOHN: Yes
22. MARY: JOHN.
23. JOHN: Yes.
24. MARY: MAY I ASK YOU SOMETHING?
25. JOHN: Go ahead.
26. MARY: IS THE DOOR OPEN?
27. JOHN: No
28. MARY: I SUGGEST THAT WE GET THE DOOR OPEN AND THEN YOU MOVE.

Note the non-hierarchical nature of the dialogue. John's initial plan gets interrupted by Mary and is never reactivated. It is the goal of the conversation that persists and keeps it on track.

1. JOHN: Mary
2. MARY: YES
3. JOHN: I want to explain something.
4. MARY: GO AHEAD.
5. JOHN: If you move, nothing happens.
6. MARY: I DISAGREE. IF YOU MOVE, WHEN THE DOOR IS OPEN, YOU CHANGE POSITION.
7. JOHN: I see.
8. MARY: I SUGGEST THAT WE GET THE DOOR OPEN AND THEN YOU MOVE.

After further planning in order to find a way of getting the door open, they construct a plan and John changes position to IN by moving. But it's not that simple...

1. JOHN: Mary.
2. MARY: YES.
3. JOHN: I want to tell you something.
4. MARY: GO AHEAD.
5. JOHN: I have moved.
6. MARY: I SEE.
7. JOHN: Lets assess the result of my action.
8. MARY: OK.
9. JOHN: I have changed position.
10. MARY: JOHN
11. JOHN: Yes
12. MARY: I WANT TO TELL YOU SOMETHING.
13. JOHN: Go ahead.
14. MARY: YOU ARE OUT.
15. JOHN: I disagree. I have changed position.
16. MARY: YES
17. JOHN: I am now in.
18. MARY: RIGHT.
