Don't Call Me Mr., Mrs.

I don't know what it is, but an unusually large percentage of people, mostly women, call me Mr. Zak.  I hate it.  It's mostly at work, either from patients or co-workers.  I don't know if it's a desire to lengthen a mono-syllabic name, to condescendingly validate my professional status while still being young or what.  I do know that I don't want people always calling me Zakary, and I don't need the "respect" of the "Mister" preceding my name.  The whole Title-First name thing bothers me.  From Dr. Phil, to the Dr. First Name in tangents of my social circles, it rubs me the wrong way.  Artificially being raised up by a title, but then made accessible by your name seems transparently insecure.  Thus, I refuse to validate peoples neurosis and refer to them as such.  Call me old school, but I'll stick last names with titles, and first names shall stand alone.
