Zvipe iwe vhiki imwe kana mbiri kuti ujairane nadzo.Vamwe vanhu vangada kureba semwedzi.
Iva nechokwadi chokuti unonzwisisa mirairo yachiremba weziso rako pamusoro pemashandisirwo ayo.
Pfeka malenzi ako matsva kakawanda sezvinobvira uye rega kupfeka mamwe magirazi ako.Ichaita kuti kugadzirisa kukurumidze.
