He looped around again, and I could hear him coming up behind me, making the sound of his favorite Pokèmon character, Pikachu. He seemed to do that when he was happy and content, like a cat purring. I do not even know if he knew that he was doing it, but his blue eyes were bright and playful, and it seemed the most natural thing in the world for him to express himself with a hearty, “peee KAAA chuuu.” He tried to slow down when he came up alongside me, and started to lose his balance, but as I reached out a hand to steady him, he reached out for the fence, steadying himself without any help from me. I do not think he noticed my hands go unceremoniously back to my side. When we got to the park, he skated on ahead, leaving me behind.
