When the queen entered the house, the woman gave the queen a big hug. Everyone was appalled that a mere commoner (albeit from the US) would dare hug the queen. The lady said something to the effect, "When I have visitors to my house, they get hugs."
I like to think that the queen needed to be subjected to the "protocol" of a loving household in the projects.
Generally, it is the guest rather than the host who conforms to protocol.
I think it's good when someone that thinks they're "all that" gets a little lesson in humility.
it was the woman's house--so the hug was appropriate.
