Manege de Zonnehoeve - The sweetest pony

Dexter is Jasmijn's pony, or at least, he was Jasmijn's pony. They cannot win any prizes together, so Jasmijn 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 is now eighteen. Who wants it anymore? Dexter hopes that Daantje will buy it, because he feels a special bond with her. But is this forever? Or will she get tired of him too?
