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.
