Trying to remember a word- please help me

Perhaps you were thinking about clincher. I've looked for good clinchers to many of m comments.

You want to end the conversation with a positive note. Concluding the conversation maybe. How about synopsis or conclusion, wrap it up, summing up, finale or summation. I think in writing it is called the conclusion. When you readdress all the subject matter and then end it on the positive note.

Is it either of these two? : confabulatio or colloquium contrario? Contrary? Sorry I can't help any further. http://en.wikipedia.org/wiki/List_of_Latin_phrases_(full) (the link I used.. latin phrases)

Touche? Is that it? It has a meaning though so that may not be the one your looking for..lol.

I'm not sure what the phrase is. I looked up "agree to disagree" and Wikipedia said it's "a phrase in English referring to the resolution of a conflict", but I don't think that's exactly what you were looking for. There is are the words cliche and platitude, but they aren't necessarily used to end conversations...I don't suppose the word you're looking for is farewell...? I tried searching but I couldn't find anything closer to what you might be referring to.
