# first of all:

#   ok?
          "ok."

# but:
#   when a thing
def   hits_the_ground_from the_height
#       if we can assume that the
            remaining_energy = the_height

#   then we can say 
      if remaining_energy
          that_the "thing uses some of the #{remaining_energy} to bounce"
#            and
            rises_to the_next_peak_from(the_height)

      else
#     the thing just
      rests
#     and that is the
      end # of it

#           we assume that

         else
#          the thing is no longer bouncing
#             percievable to this observer, anyway...

#    when a thing
#      is dropped
def     from a_height # it 
              hits_the_ground_from a_height
end

# likewise,
#    when a thing
def   rises_to a_new_height
#       then it will fall
          from a_new_height
end
