Funnily enought, the line that hurt the most for me was one with no excuses.
"NO."
Pretty much had the same thing happen to me, nistelrooy, about four years ago. She said it in such a nasty, patronizing, "you are a total goon" way, made all the worse by the fact that we had occassionally chatted during the previous three years. The good thing is it was such a heartless bytch move on her part that after a day I was like, damn, she truly wasn't worth a crap to me in the first place. I think she thought the same thing, and let me tell you why...
I didn't see her until about a year afterwards, when I was with a friend in a local restaurant, and she was sitting with some of her friends at a nearby table. We knew each other were there, but I didn't really care. When it was time to leave my friend and me happened to be passing her table as she was returning to her seat from the bathroom. For a brief second our eyes met.
As we exchanged basic "hi's" to each other as we passed, I was able to look right into her eyes with total fearlessness, because I knew she was nothing compared to the women I have as my friends and in my family. My body language said so much, "Hi, you're worthless" when I just shrugged her off and went on my way. She was so visibly nervous and had such a look of fear in her eyes and in her voice, it was almost as if she had expected me to haul off and hit her. It was pretty obvious to her that she knew she had been a heartless bytch, too.
I really enjoyed that. It was terrific.
