Text: FATHER  You know, Kaethe, even though you are my sister, and this money was legitimately inherited from our parents, and I'm giving it to you in order that you may pay for a lifesaving sweat-gland-transplant, which will finally enable you to dress properly, I'd bet, to an outsider, this whole scene would look awfully fishy.
Entailment: Kaethe, I'd rather give you my inheritance so that you get the treatment you need.
Contradiction: Kaethe, I need this inheritance money more than you do.
