A giggle escaped him the moment he saw it. The little brick bungalow, the scene of countless epic battles fought with water balloons and cardboard swords, was up for grabs. He'd never expected to see it again, not like this. A thrill, like a forgotten sugar rush, coursed through him.

He pictured himself, a ten-year-old whirlwind, zooming around the house. The creaky stairs, the dent in the wall from a particularly enthusiastic game of indoor hockey, the swing set heโ€™d spent hours on. The memories were a symphony of scrapes and laughter and childish rebellion.

He spun his chair around, eyes scanning his own grown-up living room. A wild idea sparked in his head. He reached for his phone, already devising the perfect, albeit slightly mischievous, plan. It was time for a little bit of fun, he thought, a secret weapon locked and loaded.
