Existential Fairy

It seems to take an int’rest,
though in what we can’t be sure –
this existential fairy pest –
this “guardian” – less pure

in virtue, from what we can see,
than fairy tales suggest;
it flies with some authority
but if this is its best

at causing happy things to be,
much less to make them rock,
we’d just as soon it took a pee,
or knit an argyle sock.
