Ndicho chikonzero nei Mambo Iyeyo zvino ari kundikumbira mashoko panhau iyi, kana kuti kutsanangura zvakajeka zvokuti kunyange vanhu vasina ruzivo rwesainzi vanogona kunzwisisa kuti nzira iyi inofanira kuvapo. Kunyange zvazvo ndichiziva kuti hwaro hwahwo huri muchimiro chenyika chakakomberedzwa, zvisinei, kuti ndiite kuti ndinzwisiswe zviri nani ndokubetsera chirongwa chacho, ndakasarudza kuratidza kuti nzira yakadaro iripo kupfurikidza nemepu yegungwa yakagadzirwa zvikuru. Nokudaro ndiri kutumira Changamire mepu yandakadhirowa ndimene, pandakaratidza mahombekombe nezvitsuwa izvo zvinogona kushandiswa senzvimbo dzokubva apo mumwe munhu anotanga rwendo rwakadaro uye parwendo urwu anochengeta nzira yakatsiga yokumadokero
