The relentless pounding from next door had always grated on Benโ€™s nerves. Today, however, as the sun warmed his face, a sudden urge for mischief bubbled up within him. He grabbed a small, inflatable T-Rex from his son's toy collection.

He knew exactly what to do. With a devilish grin, he climbed onto his roof, the inflatable dinosaur clutched firmly in his hands.

As the construction workers took a break, he carefully positioned the T-Rex, as if it was peering over the edge of his roof, surveying the chaos. Watching their reactions was more entertaining than anything he could think of.
