Kulembetsa kwa mtengo wotsika kungathe kumakuwonongerani zambiri
Zida zothandizira anthu kumvetsera zimatha ndalama zokwana madola zikwizikwi, mtengo umene nthawi zina umakhala wovuta kuwamvera ngati mutayala pang'ono kumva. Kwa anthu awa, thandizo lozimva kumva lingakhale lothandiza, lopulumutsa ndalama.
Kuyesera koyambirira sikulephera Kukhazikitsa Thandizo la Ogulitsa
Zipangizo zamakono zothandizira kumva zimakali akadakali ndipo sizinali zovuta.
Mmodzi mwa anthu oyambirira kupita nawo kumsika anali thandizo la kumva la mbalame ya Songbird yomwe imakhala ndi moyo wa maola pafupifupi 400 (masiku 16). Ndi nyimbo ya Songbird, simufunikiranso kudera nkhawa mabatire . Mukanangouza wina watsopano pamene wachikulire adalephera ndikuwombera m'makutu anu popanda kukangana kapena kusokonezeka.
