"I know I'm Not Pretty"

The lack of confidence some people possess saddens me greatly. I've never met a truly ugly person. I've met some that had a defect or acted ugly, but I would never think to myself.... that person is ugly. I might think condescending things.... they're fat.... they have bad acne... etc., but never have I thought or muttered something so horrible.
Today, I was working at VS; and a women came in w/ a return. She walked through door and I smiled and said hello, but my manager struck up a conversation with her and I continued the work I was doing. When you first open your gate in the morning, the last thing you want is a negative sale. So maybe I looked annoyed.... I don't know. Anyways, this lady is a regular at my other job. She claims she comes in and buys flowers from me everyday..... but um, not everday. Maybe like every other week. She annoys me slightly. While I was helping another client, my manager and her have this conversation:
"That girl over there works at Ukrop's, doesn't she? She acted like she didn't know me, and I buy flowers from her every day."
"yes ma'am she does. I thought I saw her say hello to you."
"Well, I know I'm not pretty, but neither is she. She should look in the mirror."
"Well, ma'am I think that was a little uncalled for."
I'm not quite sure how she got onto that track, but when courtney was telling me about it, I just thought about how sad it is that someone could even begin to start a sentence off with "I know I'm not pretty" much less end it the way she did. It made me just a little more thankful of my own confidence and the person that I have become.
