Who is this nocturnal visitor?

Who is this nocturnal visitor incognito?
Is he seen only by a few, or naked eyes?
does he slip in like a cat for kind or for cash?
or for both, or with pseudo-kindness,
like the itching dandruff, creating a bald,
Bugging all the time, draining your purse?
People with all devious thinking imagine
That the visitor is fond of my house,
yet till today I have not seen the mysterious,
nor I am inclined to catch him red –handed,
when the imagination runs devious,
when the devious thought takes
further a crude sinister turn,
when my guardian angel is vigilant,
this acrimony would only lead to acrobatics,
Undoing all nonsense and hypocrisy.
you can wake up a sleeping dog
you can not infuse sense and sanity
in a seemingly deaf and blind
man and woman who are no less than
conmen loitering the premises of the
easily gullible, causing havoc
to the good and innocent.
