He was standing on the sidewalk below, jumping up and down. A passer-by might think he was crazy, but she knew better. He always did things with good reason. She smiled at him as she walked by and murmured, "Hi." He looked around like a startled deer caught in a floodlight, but she was gone. She had dissolved into the doorway.
Maybe he's really happy, she thought, as she walked softly up the stairs, careful not to wake the sleeping house. Sometimes, when she was happy, she felt like doing that. And she felt like never, ever, ever stopping. Maybe he was that way, too. She could ask him, if she wanted to.
She went to her window, and watched him below her, jumping up and down. He was cute in a toddler kind of way. Not really her type. It didn't matter. The neighbors had whispered that he had a problem, anyways. Autism or something. He hadn't ever said much to her either way. It was just nice to watch him jump. Up and down, up and down, like a pogo stick... Why didn't people jump more often?
He looked like he was trying to catch the sky. The sky was so blue, she couldn't blame him for trying.
