B reminds me of myself in 1979. First day in William Wirt Jr. High School in suburban DC. My mom conflated a public school in America with a "public school" in England and sent me in wearing a 3 piece suit. Imagine the humiliation for a 12YO!
Jack, an African American kid walked straight up to me as I was desperately trying to become one with the insides of my allotted locker and asked with a look of mock concern: "So who died brotha?"
I didn't know what to say. Then he whispered into my ear "Now you're supposed to say "not your mama, that's for sure." We remain tight to this day.
"O people, we created you from the same male and female, and rendered you distinct peoples and tribes, that you may recognize one another. The best among you in the sight of GOD is the most righteous. GOD is Omniscient, Cognizant." (49:13)
