Flashback to over twenty years ago….

Imagine the scene: one of the most opulent buildings in the world. It’s a royal palace, not necessarily in England. A man is standing in the study of a member of a royal family, waiting for the royal to arrive. The royal’s secretary is also waiting.

Suddenly, there is total chaos in the corridor outside. Loud noises, shouts, scuffles are heard. The man turns to the secretary in alarm and asks, “What on earth is going on?”

“Oh it’s just xxxx and xxxx having one of their regular set-tos,” replies the secretary, as though such stand-up fights were commonplace. As indeed they were.
