We all make mistakes.  It's nothing to be ashamed of.  But you face a choice.  You can ignore it.  You can deny it.  You can refuse to believe it.  Is it really possible?  Did you actually make the mistake you seem to have made?  I would never make that particular mistake.  A mistake may have occurred but don't look at me.  That's what I was trying to do.  But this is dangerous.  And unwise.  What are the consequences of this non-mistake?  Will you risk more damage by not facing the truth?  And what of the messenger who brings you the news?  How would you treat him?  Some people take bad news badly.  They feel stupid, humiliated even, that not only did they make this stupid mistake, but this guy also knows about it.  How dare you walk in here and insult me like this!  Take that look off your face!  They get angry.  Some people get very dangerous when they get angry.  Some people are angry or dangerous to begin with, and when faced with bringing such a person the bad news of some mistake that he, himself had no part in causing, one might shrink from the task.  But will refusing to bring the message make the situation worse?  If you refuse to tell this asshole that he fucked something up, and things go downhill from there, who's going to get blamed then?  It's a Hobson's choice.  You're between a rock and a hard place, and other clichés.  It isn't easy. I can tell you now that I face such a situation, at this very moment.  Although I don't want to, I must inform you, that either you typed in an incorrect address, or you clicked on a link that doesn't work.  The page you requested cannot be found.
