I once knew this mzee who had a hot gacungwa/second wife or something. Every once in a while he would invite me to join them for drinks at our local. No sooner would i be seated than his dog would run in from his car run around us and go back, i made nothing of it till i met the guys bodyguard after the guy passed on, apparently the dog was trained to sniff if you have dipped your mkwajo into his gacungwa and i was a suspect. Dont imagine you can cover your tracks.
