This morning on my way to work, I watched a woman
tap/pound/hit the top of her head for at least 3 city blocks BEFORE I started to video her.  During her demonstration of her ability to play any percussion instrument, at least her cranium, her passenger joined in and began to tap/pound/hit her own head.  WHAT IN THE WORLD IS THIS ABOUT, do you know??  This went on for about 9 city blocks.  PLEASE, tell me what this woman was doing if you know.  I got so tickled and the man in the car beside me started giggling as well.  lol  What in the WORLD??  lol
