I play partners sometimes on my team with a woman who will simply not shut up. I can deal with her when we're playing a "friendly" match but when I'm really trying to win in a league match, her constant jabbering destroys my zen-like mental state. I won't even discuss strategy with her, as that sets off a long, rambling speech (she doesn't actually listen, she just talks). I generally tell her before the first game that I will not be talking during the match, but I'm sure that seems rude. On the other hand, if I completely ignore her (an almost impossible task) I seem like a jerk anyway. By the way she's a good player, and we've actually won several times together so this has nothing to do with her tennis ability. My question is can you tell someone to please stop talking without being an a-hole?
