Bava Batra 143: The Donkey and the Five Women

When one doesn't respond to a stipulation of inheritance that would go to a person and a donkey... To understand this case, a somewhat parallel case is introduced of five women, two of whom were sisters, who were to be betrothed with a basket of figs - and those two sisters cannot be betrothed in this way, because, as sisters, they cannot be betrothed to the same person. But are the other three betrothed, and if so, why? (Which is then lined up with the donkey in the first case). Plus, the case of one who sent silks to his home, some for his sons, some for his daughters, and maybe daughters-in-law. And the case of one who bequeaths his belongings to his sons (when he had only one, but also a daughter) - is that an error or intentional? Similarly, if one seems to call his grandson "son," is that effective or an error? Also, a new mishnah! With complications of family dynamics and estate-planning.
