A couple of cases of betrothing a daughter - with a cup of wine, with a package of vegetables in the marketplace. And who's doing the betrothing? The father of the daughter to the father of a son is a complicated question. And the marketplace complicates matters because it (or the vegetables themselves) may be lacking in respect. Plus, when the mother and father of the daughter each want their daughter betrothed to a relative of each respective side. Also, terumah! Namely, how the minor might be allowed to continue eating terumah, or not. Specifically, if a minor accepts kiddushin without her father's knowledge. What are the implications to the betrothal? With a dispute over the meaning of the father's silence (or lack of protest) at the immediate timing.
