What do we know about the grandmother?

M: Oh, who is the beautiful old woman in front of the house?
W: That’ s my grandmother.
M: Oh, then that must be your house in the background. Where is it?
W: No, that’ s my grandmother’s house. She lives in Kentucky. We live in Boston, about two and a half hours away by plane.
M: Then, does she live with your uncle or aunt?
W: No. Since her husband died, she has lived alone.
M: Alone? But she is so old! Who takes care of her?
W: She takes care of herself, though she is 81 this year and is beginning to slow down a little. She has a cleaning lady who comes for a few hours a week to clean house and help with the shopping.
M: But isn’t she lonely without family?
W: Of course not. She has lived in the same neighborhood since she was first married, so she knows all the neighbors, young and old, and she has lots of friends.
M: Why doesn’ t she live with you? Don’t you miss her?
W: Well, actually, we talk to her on the phone every week and visit her at least once a year, but we are busy with our lives and so is she. We love to have her visit, but we all know that if she lived with us, we might not get a-long so well.
