During my recent return to Ohio State's campus, I found an unlocked door at Denny Hall, the English building. Entire floors have been gutted and rebuilt, so most of my memories have long been sitting in a landfill. The top floors remain the same, though. Some of my graffiti still adorns the faculty men's room. And delightfully, one of my favorite profs is still there, still displaying the same poster outside her office. She served in the Vietnam War. On the first day of class, she told us that we could refer to her either as "Professor" or "Captain." Our choice.
