I love the effort and respect your motivation and intentions, however there is one thing the “greatest generation” is not so great at and that’s flash mobs. This gathering of the jiggling geriatrics is less of a flash mob and more of a community center get-together. I dig the fun they are all having but let’s not get ahead of ourselves and start praising these folks. If you’re going to do a flash mob then please make it incredible. If you’re the old southern style plantation owner dude in the hat who looks as if he is leading the mob, you cannot be off beat every single step. Back to the home with you and back to doing what grandparents do best, making me cookies and handing out horrible tasting hard candies to stranger's kids.
