The pony is mad. She can go from a relaxed walk to a flat out gallop in seconds if something spooks her, and she won’t stop until she practically crashes into something. I’ve seen her buck, rear and spin around in circles. She’s completely unpredictable and I don’t even trust her on the ground. As far as I’m concerned, Alec’s welcome to her, and he relishes the challenge. For some reason, he loves that pony most of all. Perhaps it’s because no-one else would give her a chance, that they’d written her off as crazy, mean, dangerous. Alec admires her independent spirit, I think, and maybe he likes that she still has that strength of spirit, that she still challenges him every time he rides her. He can’t completely dominate her, and he doesn’t try. He wants a partnership with her. And slowly, slowly, his father is taking that away from him, bullying the mare and his son at the same time, seeking to fit them into the same mould, the only one he knows. The strong succeed while the weak fall behind.
