But not as close as she portrays, IMO. The latest voicemail released has revealed that NG only found out that SS was building the studio a week before it was scheduled to be opened. She is prone to untruths and exaggerations, IMO. Which seems a common thread in this case.
I agree NG has inflated her personal relationship with the S family and possibly with VF. The S family was not her only client, she wasn't there every week day. She may have cleaned there sometimes, but obviously at least one other person worked with her or alone on other days. You can have the same doctor, mechanic or landscaper for 20 years. A certain amount of loyalty develops, but that isn't the same thing as a friendship. If the person wouldn't do for you for free what they're doing for you for pay, they are an employee/contractor.
Before I started preaching, I meant to say that her exaggerations about her relationship with the S family don't mean she lied about things that can easily be confirmed, like if she was at the dojo when AS called. I think she's smart enough to know what she can get away with, but maybe not.
