Bypasses are devices that allow some people to dash from point A to
point B very fast while other people dash from point B to point A very
fast. People living at point C, being a point directly in between, are
often given to wonder what's so great about point A that so many people
from point B are so keen to get there and what's so great about point B
that so many people from point A are so keen to get there. They often
wish that people would just once and for all work out where the hell
they wanted to be.
