do you admit you're wrong?

[Jeremy40]

hey guys

i am friends with a few older gentleman who had reputations around the area as being very very excellent officials. all 3 are now retired. i asked recently if they ever admitted to making a bad call to a coach during a dispute. all 3 said that they never would admit it. in there mind they knew it was wrong, but during an argument they said that they never would bow out to a coach, apopogize for a poor call, or even admit to being wrong. is this proper?

thanks
