agree, my 99 also do similar things. she just think we are bad-treat the maid, but she doesn't know there should be boundary for maid too. e.g. whatever i eat, like cake, go yum cha, 99 thinks the maid should get a share/ go with us. However, she's here to be a maid, not the GUEST of me, i give her what she needs to fill her stomach, but not to an extent that she feels enjoyed or go or entertainment with me.
The relatives especially grandparents, are the one who 'spoil' the 'rules' at home..
