Personally I don't think it's any if our business why she didn't do it! Private info is private info! According to Faye's fb, the charity knew and the attendees were happy with the reason they were given! As long as she does the jump everything else is really none of our business! If her and Aaron tweeted every single thing they do then I could maybe understand the aggrieved feeling, but they have made it quite clear they want their lives to be as private as can be and I think we should respect this and discuss what they do tweet and share, not what they don't!
At the moment we can only speculate as to why she hasnt done it, we have no evidence and I really think the fairest thing to do is wait. I don't expect her to give her reasons it is her life, her business, she isn't in the DR anymore! As long as she gives a new date and a little apology to those who turned up just to see her, that's all I feel she needs to do! Other than that it isn't our concern!
