She is actually full of fun - emotional, throwing racquets, screaming , speaking vulgar words to herself , exploding , making waves or fistpumping (very similar as some slumping balkan babe)...she is making boring match interesting...I will better watch some drama as two ladies just walking from one side to other like soliders playing push-push-sometimeswinner match
I don´t really mind, if she is throwing her racket or if she is discussing with herself. In most cases, it hurts her game more, than that of her opponents. So, who cares.
On the atp tour, some player throw their rackets and cursing even more often and nobody gives a shit.
