Dr. S and I both go to the university's gym: both very fancy, and freeeeee. He has a locker in the faculty locker room, where he has apparently met about half the male faculty so far - in the buff. He much prefers introductions while all parties are wearing pants. (In either sense.)
A couple weeks ago at Dr. S's office, another professor dragged out his summer students - "Here, meet your new biochemistry professor, Dr. Scientist!" Partly to be amusing and partly to make a point, I introduced myself to the students as, "I'm also Dr. Scientist, but I won't be teaching you in the fall, so please call me J."
Last time I was at the gym, I ran into two of his future students. One of them referred to my spouse as "Mr. Dr. Scientist", as in "I emailed Mr. Dr. Scientist" - all the professors here are Dr. So-And-So, and heaven forbid the students should call them by their first names. (The South, you know.) So I suppose by extension I'm Mrs. Dr. Scientist. I doubt any of them will call me by my first name. The mind boggles.
A friend then pointed out that the alternative was "Mrs. Scientist", which would be even worse.
(I gave the students a ride home, too, because it started pouring down rain. Small towns: if you don't meet someone you know, every single time you leave the house, you're doing it wrong.)
