I hate them normally and just keep them brief while batting.
Everyone manages their inning differently. So both batsman invariably don't want to follow the same advice.
Some conversations I have been involved in
"Lets set ourselves targets of ten runs at a time,. :"Nah thats stupid"
"Lets try to tick it over at about 3 an over." " I disagree lets just bat".
"Man this bowler is bowling well I am going to try to pump him over his head to unsettle him" "Oh man that has upset my concentration"
"Lets bat like we are 10 and 11" (said to me when we were two down)
"You've faced too many dot balls it is time to work some singles".
In one team I played for I could predict when a wicket was going to fall. The wicket would be preceded by an involved discussion between our two batsman in the middle cooking up some ill fated plan.
These days I just bump gloves and say "keep going mate" and walk back to my end.
How about you - do you find the mid wicket conversations helpful. What are some of the more amusing conversations you have had?
