[188] Householder's son, on four grounds the one who is all talk (vacīparama), an enemy in the guise of a friend, should be recognized: he shows hospitality with what is past; he shows hospitality with what is yet to come; he offers assistance with what is useless; when tasks are at hand in the present, he pleads his own misfortune. On these four grounds, householder's son, the one who is all talk, an enemy in the guise of a friend, should be recognized.
