Solve for X

A good friend, someone you do not even know,
named X, of course, as all such friends have been,
claims that “children change everything – but
we remind them – we shout
that nothing has changed but change itself
that the world has been the same
, the world did not exist before
these children – that the world was created by
and will be destroyed by them.
If this is, as X says, what X means,
then X can have it, along with
stupidity, along with the liquid pleasures
and the long window from the den.
