smallfoothk, agreed what you said, but sometimes need to be very cautious with the claimed "qualification" of the maids. I employed a maid recently. The maid claimed to be a former primary school and secondary school teacher in the subject of English and Maths in Philippines and the agent highly recommened her. When I watched the video before employing her, she looked ok.
Now she is at my home. The reality is that she speaks very rarely. Even if she speaks, her voice is extremely soft, so soft that I cannot hear her even when I stand right next to her. Originally I had some hope that she can accompany the young kid to do homework, but it turned out that I have employed someone who does not speak at all. Even when she "reads" story to my kids, her voice is as quiet as a mosquito!!! I really wonder about her experience of being a teacher. Maybe she did it so badly that she was fired and then left her country.
