Riding school de Zonnehoeve - The sweetest pony

Dexter is Jasmine's pony, or at least, he was Jasmine's pony. They can't win any prizes together, so Jasmine gets a better pony. Dexter is sold. It's already the fourth time this has happened, no matter how sweet he is and how hard he tries. He's eighteen now. Who wants him now? Dexter hopes that Daantje will buy him, because he feels a special bond with her. But will this last forever? Or will she get tired of him too?
