The crisp autumn air bit at Thomas' cheeks as he strolled along the riverbank. He skipped a stone. It skipped five times! He laughed, a deep, full sound. He was so happy.

He spotted a wallet, half-buried in the mud near a weeping willow. It was fat with money.

A grin stretched across his face, wider than the river. He knew what he would do. He’d treat himself and his family to a weekend getaway. Somewhere warm, somewhere with a beach.
