Yakavakwa kubva kumhando yepamusoro, purasitiki yakasimba, madhiri aya akareruka, anoshingirira mamiriro ekunze, uye ari nyore kuchenesa, achivimbisa kushanda kwenguva refu munzvimbo dzinoda.
Inowanikwa muhukuru hwakasiyana, maumbirwo, uye mavara, madhiri edu anogona kugadzirwa kune ako chaiwo zvaunoda. Kunyangwe iwe uchida zvidyiro zvekudyisa zvipfuyo, zvigadziriso zvekuchengetera mvura, kana dhizaini yakasarudzika yekushandisa mumaindasitiri, tinoendesa zvigadzirwa zvakagadzirirwa zvinosanganisa kushanda nekusimba kwakasarudzika. Batana nesu kune tsika dzepurasitiki madhiri anotsigira bhizinesi rako kuita nekuita kwakavimbika.
