Professor Adeline Cross had given 4,127 lectures in her career. She knew this because she had kept a tally in the back of her planner since 1989 — one hash mark per session, five marks per row, neat as a picket fence.
Lecture 4,128 would be her last.
The hall was full. Not the usual scattering of half-awake undergraduates, but packed — former students, colleagues, even the dean, who hadn't attended a lecture since his own student days. The rapport Adeline had built over four decades had filled every seat.
She had planned to be eloquent. She had drafted remarks about the nature of knowledge, the responsibility of education, the quiet joy of watching a student's face change when an idea finally clicks. She had rehearsed them in the bathroom mirror.
Instead, she was candid.
"I don't have wisdom to impart," she began. "What I have are regrets. I regret every time I was too busy to meet with a student who needed help. I regret every paper I graded too harshly. I regret the years I spent chasing publications instead of chasing understanding."
The room was silent.
"But I don't regret this," she said, gesturing at the hall. "Not a single Tuesday or Thursday at ten fifteen."
After the applause, after the flowers and the handshakes and the cake in the faculty lounge, Adeline walked across the empty quad. The spring air carried a particular scent that triggered a sharp pang of nostalgia — cut grass, coffee, chalk dust — the smell of forty years compressed into a single breath.
She kept walking.
