May be its because I am slow witted but usually don't talk when I am batting. I actually enjoy when others talk to/at/about me but I just smile, sometimes giggle, might say a word back but its more me agreeing with what they are saying about me lol. When bowling I never ever say anything, i get really mad but don't utter a word, just internalize it and get back him with my bowling. I don't believe in appealing when I don't think some one is out, or having a word when they hit me for runs.
Last season in one game was the first and only time I started talking to the batsman while i was placed at short cover, he was newly married and his wife was there to watch and it went along the lines that if he didn't do too well she might not be impressed and instead might be interested in the other batsmen on his or my team. I apologized after the game as I didn't think it was required to say things, although i hadn't cursed or anything bad was said all innuendo and implied...
