Wife and servant are the same, but only differ in the name. Lady Chudleigh

The wife became the head servant. Friedrich Engels

In May 1854, at the age of twenty-five, Arthur Munby stopped a maid-of-allwork in the street. The encounter was as casual as any of the hundreds that filled Munby’s wanderings, yet the woman was destined to become his lifelong companion and wife. Almost immediately, Hannah Cullwick and Arthur Munby embarked on an intense but clandestine love affair that lasted the rest of their lives. After nineteen years, they married secretly, though they lived in the same house for only four years and then, to all appearances, only as master and housemaid.
