I am not 24/7, only in my head, but when I'm dressed and out it does hurt to hear the sir, or he, but I always take it in context. Was it a slip or was it truly said to be mean or embarress. I just simply correct the mistake, and educate the person. I did once respond back to a saleswoman as sir, and said how did that make you feel? I think you have to take each incident on its face value. I aslo think that we are making progress but it's going to take at least another generation to get it right.
