She's doing the best she can (we are all just satellites).

“I certainly believe we all suffer damage, one way or another. How could we not,except in a world of perfect parents, siblings, neighbours, companions? And then there is the question on which so much depends, of how we react to the damage: whether we admit it or repress it,and how this affects our dealings with others.Some admit the damage, and try to mitigate it;some spend their lives trying to help others who are damaged; and there are those whose main concern is to avoid further damage to themselves, at whatever cost. And those are the ones who are ruthless, and the ones to be careful of."

Julian Barnes, The Sense of an Ending
