I haven't met a professor that I'd be comfortable with referring to as Mr. Professor smile (DW is not currently, although it's likely she'll pursue that course after the children are a little older). My original post was a bit tongue-in-cheek as I have never had to correct anyone. But when the opportunity comes up--and it generally does--it's not hard to politely let them know about DW. Given that school admin's with PhDs are addressed as Dr. So-and-so I'm not sure why we'd act any differently... ?

I definitely don't flaunt that (or what I do). In the non-academic and social world, we don't bring it up unless someone asks.
