well getting a load of strangers on a web forum is not going to change anyone's mind, so you are best just keeping out of it.
i don't understand why she would imagine she would get to keep all the stock in this situation - she knows she paid nothing for it, so she thought the ex friend should lose not only the stock but all her money too?
and the dad was just going to 'give' her a car?
i suspect your sister knows quite well she is being unreasonable but her nose is out of joint and she has also lost her job/business and thinks if creates enough bluster about it she may get something back out of it - she may get some stock or cash and saves face.
she deserves neither of course - what on earth made her think it was her place to go spreading personal business over fb?
i would have dumped her as a friend too.
she probably also knows she should not have done it but doesn't want to admit it so it desperately trying to turn the blame around
why not show her this post#?
