I have to respectfully disagree. I have a cleaning woman who cleans our home every two weeks. I really like her! We have a great relationship. A person's home is one's sanctuary. To allow an outsider in breeds familiarity and possibly a friendship. IMO. My guess is NG knew the family well. She may be close to the girls as well. I find it impossible to believe the family would not want her at the funeral. SS and AS strike me as really good people who would be upset if she was not at the funeral. I think they were close. Of course, on a different level.
My point was not that she didn't belong at the funeral but that it doesn't necessarily mean they were close. We have no idea if they were close. I haven't gotten that sense, but maybe. I think they definitely wouldn't want her speaking so much to the press. We need to be careful about assumptions here about how the family behaved. They were killed in a brutal, horrific manner and its tempting to attribute a level of nobility to them because of their suffering, but we just don't know. I have seen no indication that NG played a role in this family beyond the housekeeping, either from the reports or from those I know who were close to the family. They had a lot of people working for them. A lot of people came into that house.
