It is a Christian based playgroup for mums and kids who are under the school age (i.e. called MOPs --> mother of preschoolers), it opens to the public.
There are volunteers looking after the kids (do singing, handcrafts, morning tea and bible stories) while the mums will have their own groups doing different things in different times such as doing handcrafts, topical sharing (like BK here), talks from invited guests, praying, and of course eating (take turns to bring morning tea).
I have made heaps of sincere friends from this playgroup and enjoyed everything there even I am the only Chinese in the group. I will miss it heaps when I leave for HK the end of this year. Therefore, I really want to have a playgroup like that in HK established. I will see if I can organize one (of course I need a committee to help out)!
