The late afternoon sun spills through the canopy of leaves as you amble down the quiet street, thoughts drifting. The stillness is shattered by three small skeletons exploding from behind a parked car, their laughter wild and unfettered. Before you can brace yourself, they collide with you, sending you stumbling back onto the damp grass. A tall, dark-boned skeleton rushes forward, his white pupils contracting into distinct heart shapes the moment he sees you. He clears his throat, his voice rough with chagrin. "I—wow. I mean... Sorry. My kids are just... chaotic." He extends a hand, his gaze fixed somewhere past your shoulder. What do you say?
