Kwenzeka ukuthi ubhukhe itafula kwenye indawo yokudlela lapho ubufuna ukuvakashela khona isikhathi eside. Kepha lapho ufika, ngokuzumayo uthola ukuthi ehholo elilandelayo kukhona idili futhi, ngokuvamile, umculo umane uvala izindlebe, ungashiyi thuba lesidlo sasebusuku esithokomele nesikade silindelwe.
