Housemaids don’t cross class boundaries because house owners won’t welcome it if they do, and this behavior is part of the system of inequalities. Naturally, when I asked them to sit side by side, it was awkward, to say the least. In most cases, the house owner had to ask her domestic maid to sit beside her. The household helps were reserved. Many of them sat only after they had been repeatedly told to do so.
Indeed, you can almost feel this awkwardnes in most of the pictures!
