In principle I agree, and when I used to play in Yorkshire I was a committed walker, to the extent where I once walked off when there was not even an appeal because, well, I knew I'd hit it and it would not have felt right to stay.
Since moving down South, I've gone the other way to the extent that I now have to be prised from the crease with the crane. I don't want to play that way, but I've seen so many disgraceful displays of deliberate, knowing cheating that I came to the conclusion that I'd accept the umpires decisions but do nothing to help them out. Whether its the side who are heard chatting in Urdu about how noone will know if they count the ones as twos and add a few wides to the score or the batsman last season who stretched to drive a wide out swinger only for the keeper to catch it diving way down the legside who swore blind that the ball must have hit a stone, you do sometimes wonder what the point is!
