From Madame Bovary, a description of Emma's dissatisfaction with Charles:

He did not know how to swim, fence or shoot a pistol, and one day he was unable to tell her the meaning of a riding term she had come across in a novel.

But shouldn't a man know everything, excel in all sorts of activities, initiate you into the turbulence of passion, the refinements and mysteries of life?

Wow. I can't fence or shoot pistols either. Perhaps I ought to brush up on riding terms.
