But, HOLY COW!!! Your W's brother has liver cancer, needs a transplant, and W's own family is unwilling to communicate that to her??? WOW! She really must have gone off the deep end. I do hope your daughter did tell her....maybe it will take a life or death circumstance like her brother's (and maybe her own health) to give her a dose of reality.
