I'm glad you clarified that because I was about to completely light you up, your first statement didn't play well. You started whining about the Williams sisters when the topic was RF's groupies. Certainly whatever reason Serena showed up late was okay with the tournament officials and the WTA. It was a sanctioned event that has rules, you can't show up when you want to. If she was 90 minutes late she would have been withdrawn from the tournament & fined. Also why can't I find an article, blog entry, or even a story comment about this delay?
As for not liking her because she pouts, you must not like a lot of tennis players. Sharapova is the biggest pouter ever, more tennis players pout than the alternative.
Also fans and the media fall all over her because she's won 14 goddamned majors and 4 gold medals. She's unquestionably the greatest women's player of all time.
If you want to dislike her because she is an bad person to lines people, that's fine. Not liking her because she's done the work to be the most physically imposing player ever yet quick and fit is really dumb. Venus Williams is the most harmless, benign, boring star player on the tour.
