We have a new neighbor who owns a white dog. I always see a granny walking that dog and it is very well-behaved (unlike my dogs). It doesn't bark indiscriminately (like Coco) and it walks slowly beside Granny. So unlike Wawa who goes beserk at the sight of bushes and birds. Kai-kai is baby talk for going out. Kai means "street". It is a Hakka word. Chinese has many dialects, Hakka being one of them. Hakka is widely spoken in Sabah (my state) so even though I am not a Hakka I can speak like one.
