*"A well-behaved boyfriend should always sample his girlfriend's
opinion at no less than twice the frequency at which she changes her
mind. When the sampling frequency is too low, a
boyfriend soon experiences the effects of aliasing... with probability at
least one half, he misinterprets her mind."* **-Allen Miu**

"Often times, especially for the husband-wife situation, direct sampling
is not possible and the sampling rule is violated. In this case,
husbands---and others who face husband-like issues---must resort to
advanced learning, state estimation, and feedback-control techniques of
which the details are difficult to explain and are beyond the scope of
this exposition."
