That didn't come out clear enough,and someone will call me a moron for that, but my argument is correct, and nitpicking that won't make it right. Decades don't "start at ten" but they start on a tenth year, always. That's all I meant. 1990-1999 = 90's. 2000-2009 - 2000's. 2010-
2019 - two-thousand teens. To quote Daniel Plainview...I'm finished.
