(a) The fact that Granny asks to find George is rather ironic, and we can see it when she repeatedly states that she doesn't want to see him or hear about him, yet she wants to see. She says that she wants to tell him that she has forgotten about him. Obviously, she still has him on her mind. it has come to the point where the entire thin is deeply buried in her mind. It is probably one of the more life-defining moments in hr life, and she wants to tell him that even though he harmed her tremendously she has had a good life.
(b) The thing taken away is her ability to love or feel for another man as much as she did for George. Though this wouldn't make a whole lot of sense. it would be better to say that a part of her heart has been taken, rather than the ability to love another man. something that she is never really able to let go is the memory of the jilting. The fact that she even remembers George goes to show for that. George will always part of her thoughts.

" I want you to find George. Find him and be sure to tell him I forgot him. I want him to know I had my husband just the same and my children and my house like any other woman. A good house too and a good husband that I loved and fine children out of him. Better than I had hoped for even. Tell him I was given back everything he took away and more." (4)
