Earlier recorded here as documented on ankataa.com and consistent with Kassim Kone, "More than a thousand Mande Proverbs" (1995) and Charles Bailleul, "Sagesse bambara" (2005); ankataa.com's actual Bambara-proverbs post, fetched directly, does not contain it, and neither does africanmanners.wordpress.com's 25 Bambara proverbs.
