What is the correct quote and author for the following quote?

This is what I remember from the quote, although the words are
probably not precise:

"You learn more from a person in a fight, than you will in a lifetime of talking."

This is the closest thing I could find:

"You can learn more about a man in an hour of play than a year of conversation."
- Plato, from The Dialogs

I agree, it does sound like a parody or reforming of the Plato, which
sometimes has 'lifetime' and sometimes 'year'.
Interestingly (or not), I did some digging around and it seems the
Plato quote itself, like many supposed classical quotations, may not
be authentic. I could find no use including a source and a search
through the Persueus Project Plato translations and the Jowett
translations of the Dialogues yields nothing similar using either
'play' or 'conversation'.

pinkfreud, thanks, that sounds like it.
