I worked as a nanny for a year when I was in college, as did several of my friends, and for the most part all of us were treated with plenty of respect.
I thought is was interesting that the DUmmy said a "kid around my son's age" rather than "my son's friend" if the kid was playing with his son and his son knows the nanny well enough to like her.
If the mother is one of the SF elite, then it is pretty much guaranteed that she is a Dem.
