Dijalo tsa ga Crista di tlhoka go nowa metsi letsatsi le letsatsi. O na le dijalo di le 20. Dijalo di le 4 di tlhoka halofo ya kopi ya metsi. Dijalo di le 8 di tlhoka kopi e le 1 ya metsi. Tse dingwe tsotlhe di tlhoka kotara ya kopi ya metsi. Crista o tlhoka dikopi di le kae tsa metsi letsatsi le letsatsi go nosetsa dijalo tsa gagwe?
