Ubomi bomthi buqinisekiswa zizazinge ezibonakalisa ukukhula kwawo. Oku kungabonakala xa umthi ugawuliwe okanye kummongo othathwe ukusuka ekupheleni komthi ukuya esizikithini sawo. Uqikelelo olululo lungakho kuphela kwimithi ekwenze kuyo izazinge zokhulula kwawo, singathi nje ezo zenzeka ngokwemo yezulu ngokwamaxesha onyaka. Imithi esoloko ikhula kwimozulu engatshintshiyo efana neyaseTropika isoloko ikhula kwaye ayinazazinge zibonakalayo zokukhula. Kungenzeka kuphela kwimithi eqinileyo kwisizikithi kwisizikithi semithi; imithi emidala emininzi ihlala ingamaholo njengokhuni olufileyo kodwa lube lungaboli. Inxalenye yezi ntlobo, uqikelelo lobudala luye lwenziwa kujongwe isantya sokukhula komthi esikhoyo. Kodwa iziphumo zisoloko zingconwana kunamaqashiso okanye kunokwenza ngokuqina kwentloko. U-White ucebisa ngendlela ekungaqikelelwa ngayo ubudala bemithi emide nemidala eUnited Kingdom ngokuthi kuqhathaniswe ubukhulu besiqu somthi kunye, nesimbo okhula ngaso umthi kunye nobudala.
