The many differences between the genders have always fascinated me. (And not just the reproductive differences although those never cease to be fascinating as well.)
There are always individual exceptions, but generally, men and women each tend to be strong in areas where the other is weak, even down to the types of pain we are more tolerant to.
It's easy to be frustrated when someone has trouble with something that comes naturally to you, but my experience is that my wife's strengths outweigh her weakness by a thousand to one.
