[Secretary Visits] Kara Wrote a Will Leaving Half of Her

[Secretary Visits] Kara wrote a will leaving half of her assets to her husband, Troy, and half to her adult daughter from a previous marriage, Madison. Kara, however, found out that Troy had been spending a lot of time with his secretary, Lucy. Angrily, Kara typed on a new piece of paper that she stapled to her will, "You skunk, Troy, you take nothing. Madison gets it all." She then signed her name. Kara then took the will to her best friend, Adriana, who signed as a witness verifying that Kara meant for Troy to take nothing. Kara was struck by lightning a few days later and died. Troy told Madison that the revision to the will meant nothing because, for one thing, it was not prepared by a lawyer.
