The old piano in the living room seemed to hum with silence. Emily trailed her fingers across the keys, the ivory cold and smooth beneath her touch. Her brother, Michael, had announced his conversion to Judaism, explaining his newfound connection to the historical and cultural roots of his ancestors.

The room felt immense, filled with the ghosts of past celebrations.
