Serena Williams' Breakout

This is about a couple months old when Serena yelled and cussed everything in her throat to the chair ref at a tennis match. My little sister used to look up to Serena because she was practically her idol. Until that little event happened my sister just looks down on Serena. She thought Serena was a better player than Venus but now her idol is Venus Williams. One little call that Serena doesn't like and she swears her heart out. But to me and a LOT of others that was  not the best call we've heard.
