It might have never happened. Some authors paint Xanthippe as a horrible person, some as a devoted and caring person, and she, like most of us, was probably somewhere in the middle. If she had wanted to pour out what she had in that pot over Socrates she might have had a reason though. He largely ignored his family and his hygiene, and he spent the vast majority of his days trying to get people to see that what they believed didn't really make any sense.
Socrates is a person whom we can learn a great deal from, even if we would have never wanted to be around him in person.
