Janet,
I can't say that I treat my maid as a friend, because I don't really chit chat to her. I don't know what to talk about, I mean you can't discuss movies, TV, shopping, restaurants, politics with a maid, right ? Most of the time when I talk to her I am giving her instructions, or asking her about the kids.
But I do treat her with respect, I always ask if she has enough to eat, and enough rest. The good thing is that she never argue with me, she knows that she must always do things my way.
