OK, fine. The truth is, "we" have no "evidence" of anything, really. Other than what the media tells us, and some miscellaneous first hand info on the island from a few people here. Sorry, I just happen to use the word "evidence" with some care.
What you said was, "there is no evidence" that RG was on AFF. I'm not at all sure of that. A number of people have said she was. I don't know different. Neither do you. The stories we have read say she either met GG on AFF or on match.com, one or the other. There is a difference, but it is one of degree, imo. And it matters little, if at all.
What we are reading tends to suggest she lived a bit on the edge, by most people's standards. Personally, I have "been there", and I don't find it all that remarkable or surprising. And frankly, it almost makes me feel for her all the more, since I feel like I "know" that life, know what takes one there, and am very sympathetic.
Not that any of this matters. What matters is, where is she?
You suggested earlier that maybe her body was on land. I'm beginning to think maybe you were right on that. But where? Why can't they find her? I know they know more than we do, and it's frustrating. I think it will come out, in the end....
