One day the staff members of a zoo
called a meeting to discuss the problem
how to deal with the kangaroos
that were found out of the cage.
They came to the conclusion ,
that the cage was placed too low and decided
to raise it from one to two meters high.
But the next day the kangaroos were still at large,
and they again raised the cage to three meters.
Quite beyond their expectation the next morning ,
they saw the kangaroos still free to go about.
They were alarmed and determined
to go to all the length,
by raising the cage to the height of ten meters.
Later a giraffe,
while chatting with some kangaroos,
asked them, Do you think they
will go on raising your cage
Hard to say, said a kangaroo,
if they continue forgetting to fasten the cage door.
