Not a very good one. And one that probably had been raised in a similar manor.
What type of mother would allow her daughter to prostitute instead of getting off her backside and find employment?
She is no kind of mom! She is a pimp!
That's a mom who doesn't care or perhaps has lost control or parental influences on her daughter.
Not a mother at all !
I don't know what kind of a mother would do that, but to properly address her, just call her Madam.
I guess it would depend upon the families ideas and values considering one of the oldest trades out there.
There some states and countries that consider prostitution to be a viable business, and some people view sex entirely different then you might.
