bzzt.  try again.  it is not necessarily true that for a given blue point,
there is a "closest" red point.

draw a line through the plane.  color everything to one side of the line
blue.  color everything to the other side of the line red.  color the
line itself blue.

pick a blue point.  any blue point.  i don't care which.  your choice.
show me a red point.  any red point.  i don't care which.  your choice.

i'll show you a closer red point.
