Mirrors are more fun
Or are they really bad “luck” to smash? The self love reflection alone will even melt them I hear
Discussion
It's smashing a window to find smashed mirrors, knowing the stones could never break the mirrors.
Ironically smashed mirrors are amplifiers. And amplifiers can be arranged to boost the signal. More signal, more mirror smashing, more signal, more mirror smashing.
Some of us make amplifiers, and some of us find them.
Might have to recruit both Kali and Saraswati to solve this amplified riddle
