"Oh, you dropped your hat," Orien says, as Tiero looks down at the canopy. The hat hasn't fallen far. He slips down to the branch just above it, wraps his arms round it and leans down. "Careful!" Then, as he scrambles back up, hat back on his head, "is it a new one?" "Yes, it was my big brother's." He hoicks himself up to the fork and sits back against his trunk, adjusting the oversized headgear. "No, I don't know him. Why?" "Just curious. My uncle's meeting him, that's all. It's not important."
