Jo,
Dun be surprised if your maid actually ate the Bird's nest hor. They may 'appear dumb' but many are just faking it. Especially if they hv exp working for chinese family b4, it's unlikely they won't know what bird's nest is. But if they really dun know, next time tell them is medicine. Cos if you say is 'good for health', you cna sure they will steal to eat the next time your back is turned.
Alibaba,
Sometimes the maid is not dun hv initiative. But rather if they 'dun act smart', the lesser things they have to do. Afterall, their interests are not aligned with ours. They are here to do minimum work and earn max $$$. They are not bothered to ensure your child is properly cared for and they dun care to keep your house spick and span.
