How do I get over my low tolerance for stupid people? (One answer)

The example you gave is one in which a woman must learn to get along with someone with whom she really has nothing in common. But that's not the usual case, where you simply choose people to associate with, absent special circumstances.

As to the basic question "How do I get over my low tolerance for stupid people?", I have to ask, why do you want to get over it? What do such people offer you that represents an improvement over an empty room and few well-chosen books?
