Boundary case

Find the ambiguous instance sitting right at the edge, the one you could argue either way, then rule it in or out. That decision draws the line where the term stops applying, which clear positive and negative cases never do.

Example

In the marriage case: a text argument where you paraphrase your partner's point back, but sarcastically. Ruling it out fixes the edge. Restating counts only when the tone is neutral, so a sarcastic paraphrase is not better communication.
