Harold doesn't ride horses out of any particular love for them. On the contrary, he finds these dumb, fragile animals more annoying than anything else.

As the crème-de-la-crème of the jet-set, the Uppers rule the night. They’ve got it all, and money, champagne and titles are certainly not in short supply. They generally dislike everyone but they particularly despise “the poor who just aren’t the teeniest bit funky”. The Uppers hope that the government will finally take steps to banish ugly people once and for all.
