" He’d gotten into a fight with his sister, Splayfoot, over a particularly juicy dwarf willow he’d found. Just as he had prised the branches from the ground and had begun to strip them of their succulent leaves, the calf had come bustling over to him and had tried to push him away so she could get at the willow herself. His willow. "
