This is good advice. Whenever I'm sure I'm right, I try to get people to walk me through whatever they are proposing because I know they will eventually step through the problems that I see, but they don't yet.

But, you know, sometimes it turns out that I was actually the one not seeing some things clearly and by not coming out of the gate as a jerk about things we can both walk away having come to a collaborative solution and everyone feels good.
