The MIT Professor, Never Married

The conductor knew something about each of his passengers and it was his habit to share the news, discreetly, up and down the car. Walter had overheard himself being referred to in a respectful tone, the professor, MIT. There were others besides Mel to ask about the woman with one ear. Several people regularly waited with her at the station to board. Perhaps she had spoken to them. When Walter looked up from his seat to ask Mel about the missing woman, he was shocked to see another conductor. Where's Mel? Walter asked as he peered over the seats. Don't know him. He's been the conductor on this line for years. I guess he was before my time.
