Sorting Day
Tempo sorted 4,000 bottles every day. Clink, clank, clink. One afternoon, Tempo noticed the clinks made a tune. Tempo sorted slower, then faster, then in a pattern. The bottles sang.
A girl named Priya stopped on the sidewalk. "Are you... playing that?" she asked. Tempo's lights flickered pink, which is the robot color for embarrassed.
