Not an issue - I have been call a PITA by professional & it didn't bother me one bit.
PITA = Pain In The A _ _ you fill in blanks
PS: I was born North in what I refer to as the Capital of the South. South side of Detroit in the shadows of a steel mill. As I walked to school each I would say good morning to my neighbors - they had nicknames like Kentuck', Tenessee, Alabam', Tex, Missisip', Cracker, etc. They all got up there on those boxcars (for free plus free room & board in those boxcars & walk to work) that Henry Ford brought south for folks without a job, transportation, etc to build automobiles. That call ed Northern hospitality, do ya' know?. And you know what many stayed. A regular United Nations of the Suthern States - being young & dumb then I jist figured this had to be the Capital of the South. Didn't have American history until after I formed this idea. When I did I didn't change my mind.
Touche' Amigo!
