Michael swung his arms as he walked through the park, his pace brisk and light. The crisp autumn air bit at his cheeks, but he hardly noticed. He'd just finished a particularly successful sales call. His mind buzzed with the deal he’d landed, the bonus he was anticipating.

He spotted a discarded newspaper on a bench and sat, eager to read it. He noticed his son, Leo, was not with his friends, and had instead left his tablet on the couch. An opportunity!

His fingers, surprisingly nimble, navigated to the tablet’s social media apps. He tapped on a familiar icon. Leo had a secret account, filled with elaborate drawings, silly memes, and comments from online friends he had never mentioned. He couldn't help but crack a smile, seeing a drawing his son had done.

His eyes widened, and a grin stretched across his face. He felt light, airy. He leaned back against the bench, a contented sigh escaping his lips. His son was a secret artist, with his own world! What a pleasant discovery.
