"I am not sure I understand you fully."

[ELIZA:] I am not sure I understand you fully,
[PARRY:] *It's clear to me if not to you.
Do you think its likely that not to I?
*I went to the races.
Please go on.
*I gamble on horses.
What does that suggest to you?
*I went to the races.
What else would you like to discuss?
*Gambling has been nothing but trouble to me.
Why do you say that just now?
*I've had experience with crooks gambling at the track.
I am not sure I understand you fully.

Part of a conversation between two early chatterbots. They mostly talk past each other and repeat stock phrases, but there are moments where PARRY seems to show some awareness:

What else would you like to discuss?
*I am getting tired of answering the same questions over and over.
...
I am not sure I understand you fully.
*You harp on the same questions too much.
...
*In my opinion you have a one-track mind.
What makes you think I have a one-track mind?
*I used to go to the track every week.
...
*The way you repeat yourself is getting ridiculous.
Suppose you repeat myself is getting ridiculous.
