I only have a problem when I bail an MD out from a bad med combo (because that is my specialty and not theirs) and in the next breath they are complaining because I am not a "real" doctor (in their case, it is a good thing I was around, or they wouldn't be a "practicing" doctor anymore!).....
....not a problem with most MDs, and I don't really care to be addressed as "doctor" (I am forever correcting my students that I am just "Val"), well, except that I would prefer that my MIL would call me doctor once in a while- just to acknowledge that I have the SAME educational level as her DS! Of course, this is the same woman who called the other night and asked ME to do the shopping as it was snowing and she didn't want DS to be killed on the road!!!!
Most of the people I work with- MD, PhD, PsyD, BA, MS, no degree, or whatever, are truly good people who are VERY knowledgeable about what they do. Some are, well, pains in the rear for lack of using a "better" word, but I have a feeling that regardless of their degree they wouldn't be any different. Degrees don't make the person, but they can be a sign of hard work and perseverance. Using titles can be a way of respecting and rewarding that. Too bad that the titles "Mr." and "Mrs." have lost the respect they deserve, as well. Maybe that is the REAL problem- we have lost respect for one another in general, regardless of titles or status.
