We've moved on from My Little Pony to a cartoon called Horseland. Full of improbably slender tweens with impossibly large eyes, it also features horses, and riding instructions.
Yet it is the likely cause of my dream the other night about being in a riding lesson (I haven't been in a riding lesson in almost 30 years . . . Christ I'm getting old).
Today Clara and Winton were arguing about a character and her horse:
Clara: "Bailey's horse is named 'Aztec'."
Winton: [with the extreme insistence and inflexibility that is his everyday mode right now] "No. Bailey's horse is called 'ASS-TANK.'"
