How could she not call home once to see if everyone is good? I don't understand it.
It is like Mr. Bond tried to tell you, this is not the girl you fell in live with and M. You will not be able to figure her out and you hurt yourself trying to analyze it all.
Think of her as you would a stranger and have no preconceived ideas about what she should do or not.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
