As I tell my charming and delightful wife of 25 years (as of last week...) I have an excuse for my caveman like, knuckle-dragging behavior.
I can't help it, I'm wired that way!
as a kid my dad was a true redhead, turned brown as he aged but when he went grey, his hair came in pink. Thats when he started to shave his head...said his dad also had pink hair...Red pigment and grey hair can = pink...
