When Mira announced her retirement, the department organized a farewell lecture. The hall overflowed. Former students flew in, clutching devices they had once built. Arjun, now a lead engineer, returned with Lila; the two had founded a small med-tech company focused on accessible monitoring. He stood at the podium and spoke of Mira not in technical terms but as a mentor who taught them to treat circuits as companions rather than tools.
