She wears the gloves. She has her purse. She has her routine of signalling by movement of the purse when she wants something to end.
She is very organized. It's really amazing to watch this woman, Her Majesty, perform her duties, but again, protocol evolves on the greeting of certain people.

In effect, if you're shaking thousands of hands, your hand could get quite a twist.
