Why are some people so ignorant?!?

Yesterday, a real estate agent that used to work in our office came into my office to say hello. I had heard through the grapevine that she had made some biased comments about our adoption (why are they not adopting a white child?) When she walked in she first asked me how my son was doing in college and when I told her that he was doing very well she went on to ask me whether we were still going though with that "thing" that we were doing? I responded with "Do you mean adopting our baby?" She then said yes and had the audacity to ask me if I knew what a commitment this was? What?!*@@? Was she kidding? I have raised a son to adulthood!! Even if I had not; I am an adult. Would she have asked me that same question if I was pregnant? I think not!! I wanted to spit profanity at her and throw her out of my office but I politely told her that I certainly knew what I was doing and that I was very busy so I would have to get back to work. Ok...Lori...Breathe and turn the other cheek!
