The complaint, a terse note slipped under the door, was a challenge. Reginald snatched it up, his grin widening like a split watermelon. He read it aloud, his voice taking on a theatrical quality, "โ€˜The noise levels are unacceptable.โ€™ Unacceptable! Oh, this is rich." He imagined his neighbor, Mrs. Gable, clutching her pearls in outrage. He chuckled, imagining her face.

He grabbed his maracas, shaking them with exaggerated enthusiasm. โ€œTime for a fiesta!โ€ he declared, bounding towards his stereo. He cranked the volume, a samba beat filling his apartment, and started dancing, his limbs loose and free. The apartment, usually tidy, transformed into a makeshift dance floor.

He caught sight of himself in the mirror, his reflection mirroring his excitement. This was going to be a fun night, he realized. Maybe he should invest in a fog machine.
