OT: Is there a polite way?

Buy him a book.

The guy is 71 years old... and obstinate :-( ...Jim Thompson

Give him some of your viagra.

Give him a detail analysis of the simulation, it's probably over his head and he might give up and pass it on to someone who knows.

Sometime helping speaks loud words.

Oh, a stubborn old geezer. Well, it's a good thing that you're not experiencing, like, cosmic justice or anything.

It really is a wonder drug! And I say this as a 36 year old...

I wouldn't know as I was merely making a joke about both the old man, and 'the old man'.

I find it hard as hell, but it's been very effective for me in the past to take someone who's being obstreperous and negative, strip the emotion from what they're saying, and then respond to them as if they'd asked me questions in a calm and professional manner.

I've had it completely fail to work, too. I've rarely had it backfire, but when it does it's a pretty good indication that some personnel rearrangement is in order.

If you can do it in front of witnesses then if it completely fails to work on the obstreperor it at least has a chance of working on the witnesses, and changing who listens to whom.

I sent overwhelming data package at noon... so far, total silence >:-}

Loud words may be next ;-) ...Jim Thompson

That's what I did at noon today... silence follows.

"obstreperor"... I like that >:-} ...Jim Thompson
