I would say that like most married women with overbaring husbands, Kate tamed Petruchio, although Petruchio "thought" he tamed her!! The gentleness she exhibited at the final dinner banquet was her manner of "taming" him and allowing him to think he tamed her. It goes on every day in households across the world. Probably happened in Shakespere's home, too, and that's why he could write about it so realistically. He must have been a great observer of human behaviour to have captured human emotions, reactions so well, and, for his plays to have lived so long that they are still relevent to human emotions, today. I love his works! They are the best!!
