In the seven Harry Potter books we are given, through observed events, insights into the personalities of the major adult characters such as Dumbledore, Snape, James and Lily Potter, Hagrid, the Weasleys and even Mister Crouch.
We see them dealing in personal ways with family and friends. But we never see McGonagall as anything but a teacher. While we do see different aspects of her as a teacher – she is both strict and stern but also caring – we never get a chance to see beyond that.
I always wondered while reading the books who she is really and how she came to be who she is.
Has Rowling ever said why she didn't give us a better understanding of Professor McGonagall?
