I am sure that the OP appreciates you re-writing her report to make her sound less self-centered and more of a victim.
And yes when someone puts their "self centered" needs over that of their kids..you better believe that I(and others) are going to call them out on that. If you think that someone who is currently out of a job, supports a child, and uses her life savings to pay for ELECTIVE surgery is using sound judgment..well unfortunately there is not much I can do about that. If you think that someone should stand on the sidelines and not try to bring that to their attention, then again not much I can do about that either.
She seemed more concerned about how she "says" the doctor mis-informed her rather than the money. Because just based on her report she still would have gone through with it if it was the surgery she says she wanted. She also mentioned two procedures, why would she not go through with the tummy tuck? It was only the facelift that seemed to be in "dispute".
Now perhaps she did come to her senses and realize she couldn't really afford it. If that is the case, what would give her more sympathy and a better possibility of her getting her money back? Would it having her say that the doctor "lied", or saying that she messed up? But then if she lied about the doctor, who knows what else she lied about? Unless the OP updates this report we will never know.
As for trying to relate this to a car, it is good that she did that. She had some very big misconceptions. Because she posted that, she could be informed that she was incorrect. Possibly saving for from additional "mistakes" in the future.
