The car ride was long, but as soon as Noah saw the familiar outline of the neighborhood, a sense of effervescence took over. He felt a childlike excitement bubbling within him, a need to experience the world with a sense of wonder. He even rolled the window down, letting the wind rush through his hair. He could not wait to see his childhood home. He'd planted the cherry blossom tree with his best friend. But when he arrived… just a stump remained.

A whoop of glee escaped his lips. He spun around in circles, his arms outstretched like a conductor about to lead a grand orchestra. "Game on!" he announced to the empty street, his voice filled with an infectious energy. "Time to make some new memories!"
