The relentless drilling had been driving Daniel mad. But today, something shifted. Instead of gritting his teeth, he found himself tapping his foot in time with the noise. He even started a counter in his head, mentally tallying how many times the drill had whirred.

He grabbed a can of bright yellow spray paint. Outside, he spotted the builder, head bent low, meticulously measuring a piece of wood.

With an exaggerated flourish, Daniel drew a giant smiley face on the side of his own house, directly facing the construction. He felt a surge of buoyant energy course through him, making him nearly collapse with silent laughter.
