I have two major ones that set me off...First is anyone other than my Hubby, my two best male friends, or my Mom and Auntie calling me "Little Girl". From Hubby it is a term of endearment, from my friends, who have known me most of my life, it is an endearment, a nick name, and a slight jab at my nautural speaking voice, Mom and Auntie raised me, so that is self explanitory, and it is NEVER said in a derogotory way.
I am a 5'8" 230 pound mother of three...there isn't anything little about me, so Mr Person at the auto parts store, junk yard, or anywhere else you seem to think women shouldn't be, calling me 'Little Girl' just loses you my business.
The other one that really bothers me is when someone asks what's wrong, and my response is None of your concern, Don't worry about it, or Nothing do not ask "No really, what's wrong? You can tell me"
I assumed when you first asked that I could tell you, if I wanted to tell you I would, but it is either A) none of your concern-so private or sensitive or just something you don't need to know, B) Don't worry about it-should be self explanitory, you do not need to worry, or I know what is wrong, but it is silly and stupid and I know I am being irrational and do not need you to tell me this, or C) NOTHING I will not say that nothing is wrong, when in reality something is buggung me, I had an ex who did this, it drove me nuts, I vowed never to say that nothing was wrong unless truely, nothing is wrong.
