A mischievous grin took over Thomas's face as he saw the fluffy white dog, Snowball, emerge into his yard. He bent down and picked up a large, slightly mossy rock.

"Snowball, you rascal," he murmured, his voice laced with amusement. He began to slowly back away, his eyes sparkling.

Snowball barked, tail wagging furiously. Thomas made a pretend show of throwing the rock, and, as predicted, the dog jumped backwards and started running. Thomas couldn't stop grinning.
