Monga makolo, ndife okonzeka kuchita chilichonse kuti ana athu akule mosangalala komanso athanzi. Timawatemera ku matenda osiyanasiyana, timadandaula ndi mphuno zawo, nthawi zina timawona kutentha kwakukulu ngati tsoka lapadziko lonse. Tsoka ilo, si makolo onse amene akudziwa kuti akuika thanzi la ana awo pachiswe powachulukitsira mankhwala ndi zakudya za nyama m’malo mwa zakudya zopanda mafuta m’thupi.
