An example of quitting prematurely is if Mr. Girl goes "You know what, I don't want to talk about this topic anymore, we can either stop here or move to a different point" and Kidology insists on not moving on, then Max leaves.

Another example is if Mr. Girl goes "I'm tired of looping these topics with you. This isn't productive. This conversation is over".

If towards the end, after going through all the topics the can think of and either of them say something like "Anything else you wanna talk about? No? Alright thanks for having this convo", that means Mr. Girl did not quit early.
