FWIW, like Dr. Black, I occasionally dig out my title and try it on for size.
I admit I sometimes do so when making dinner reservations at hoity toity places.
Mostly, though, I keep it ready and polished especially for when when fatuous old men call me "Miss."
And if I were a petite, beautiful blonde like Dr. Jill Biden, engaged in the tough work of teaching adult students English, I’d be sure to whip out that title on regular basis. You got one of these, inane LAT journalist?
I didn’t think so.
And frankly, much as I loathed Dr. Condi Rice as Secretary of State, I do find it annoying that she (and Dr. Maddie Albright, for that matter) never got called Dr. Secretary of State even while people still call Dr. Kissinger by his title.
