Only men and men should shake hands. a man shaking the hand of a woman is inappropriate, when you meet a woman, just nod to show you acknowledge her. If a woman comes up to me and puts her hand on my shoulder to talk to me, I will rapidly step away and yell out.. " BAD TOUCH!"  so all my co- workers will know that touching me is inappropriate.  this lesson is for you Sen. Kruse. learn it, embrace it ,live it.
