Another universe technician popped in.
   "okay, guys.  So."
    The technicians and sewer surfer were irritated to be interrupted.
   "1.  That universe is fake.  It's just part of some list spam.  It's
   okay if it's temporarily upside down for a bit."
    "2.  This particular universe is fake too.  It's also just part of
   some list spam.  So if it seems like the world is over, we can fix it."
   "3.  Yes, this universe exists for the sole purpose of making things
   better in the real universe.  We hear you, we're with you.  We don't
   understand each other well, which is sad."
    "4.  In the real universe, we're worried about producing too much list
   spam."
    The technicians and sewer surfer apologised.
   "I'd like to flip back this little 'fake' universe for the poor
   pedestrian.  I think that will help the list spam.  Can you use your
   universe powers to flip it, even if it's messy?"
    The universe with upside-down gravity rotated back so that gravity was
   normal again, because these are just words in an email.
   Everybody cheered!  The sewer surfer looked regretful but relieved, and
   ran out of the technician room to return to their safe sewer.
   "So the plan is to hit 'send' fewer times.  It might make things more
   interesting.  I think you go as the pedestrian."
   Back in the pedestrian's reality, gravity had rotated upside down
   causing a frightening flood, but everyone seemed okay.  The lotus now
   had a pool of water in the street to float in.
   "Oh my goodness!" said the pedestrian.
   "Oh my goodness!" said [1]infura.io .
   "Everyone all right out there?" said the gutter brick.
