Williams Sisters Abandon Fed Cup team with less than 2 weeks to go for finals

I am hoping they have a good reason, maybe an injury. Because if they just pulled out to do something else with their time...I can understand why people talk about the arrogance of American athletes. Serena Williams in particular seems to think she is pretty far above everyone else, and not just in the tennis department. I don't want to think badly of her though. She's been through a lot, including the death of her half sister a couple of years ago. Still, I wish she would show more regard for her sport and its supporters.
