I get the feeling with the recent meetings of Presidents at former President George Bush's funeral that one thing I found common is how much the wive's seem to control the situation. Everyone from Melania to Jimmy Carters wife Rosalynn seem to direct the flow of their husband. How President Trump looked at the book provided to them, Bill Clinton not reaching over to shake President Trumps hands and even Jimmy looking for a card that was included in Hillary's readings not his where Rosalynn seemed to work on trying to temper his reactions.
In almost all cases it seemed that the wife had some influence maybe more then people understand. Melania made it an effort to walk over and shake both President Obama's and Michelle's hands seem to setup the moment where President Obama seemed more open to being polite to President Trump. I know people will disagree with me but I felt like these woman really indirectly seem to call the shots in these men's lives.
