It's funny how all the dudes in here are siding with the guy. To me it looks like the woman has had enough of his shenanigans after years of supporting him when he wasn't doing well financially. She paid his hosi bill which sound like it was a result of drinking himself silly on cheap booze, helped him get his PSV nini nini, and now that he is on the up and up, he has decided to go get himself a ka-girlfriend. Even me, I'd refuse to leave that matatu and until saw this Betty.
But why on earth did he bite her?
